AirPlay can not connect to Apple TV: check your firewall!

Hello world

I struggled for a while with an error where my MacBook wouldn't connect more Apple TV and show a message was not to connect to ' Apple TV ':

When I tried to connect several, several times I managed to not even ask for a password...

The solution, it turns out is the firewall settings!

This could be caused due to your firewall settings:

  • The block all incoming connections setting indicates it crashes a lot - it does not really specifically mention Airplay, but she who will block as well:
  • If you want AirPlay to still work with the active firewall:
    1. Do not use the mode to block all incoming connections
    2. Check that the airplaycpxhelper application is allowed:

      ... or you can also just allow signed software to receive incoming connections


I hope this helps someone - it took my a few days to understand

  • Just send a question to the support site that I can NOT connect on my email account after auto update of 38.3.0, cannot connect to my account to check the issue!

    I just posted a question on the last update automatic 38.3.0 it is possible to log into different e-mail accounts in a profile, only the first e-mail account. My support mozilla account is linked to one of the email accounts that I can NOT connect to. Can't connect to this email account to check the issue. Your last 38.3.0 Thunderbird is useless because it is no longer possible to log in different e-mail accounts in a profile, and your support solution is useless because you need to connect to the e-mail account to check the issue.
    How to proceed?

    You can change your email associated with your media profile.
    I have 38.3.0 and I can access all my email accounts I suggest you try the initial tests:

    Start T-bird with disabled modules.
    If it works on your module is to blame and you need to activate one by one.

    Start your operating system in safe mode with active network.
    If it works probably your antivirus is blocking or delaying. (Or driver).

  • Could Not Connect To Apple TV

    As the title says... "Could not connect to Apple TV"

    Its last 4th Gen and I just all of a sudden today get this message. No changes made to do anything. AirPlay works very well on my 3rd Gen on the floor. Switch to 'Living Room' and cannot connect. Summer works well for months and months.

    Tried to restart everything. Everything is up-to-date. Disabled firewall... (don't see why this is a diff when it works fine) Nothing happens... Same message...

    I'll have to do a reset here? Or is it something else.

    Any help appreciated thanks a lot,

  • Since the update to El capitan OSX 10.11.4 on my Macbook Pro (2012) I can not connect to the app store - ideas?

    Since the update to El capitan OSX 10.11.4 on my Macbook Pro (2012) I can not connect to the app store - ideas? Im not geek so please be gentle!

    Try restarting mode without failure. To restart in safe mode, restart the computer and press on and hold down the SHIFT key until the Apple icon appears. The computer starts more slowly than usual because the disk utility checks the drive. After getting on the desktop launch the App store and try to connect. Successful or not, once you're done, restart normally to exit safe mode.

  • I can not connect to Macbook Pro iCloud

    Hello!

    I have a problem with access to iCloud on my MBP (15 inch, mid-2015) OS X EL Capitan. I can not connect on App Store to make purchases and get apps, iTunes, Messages and iCloud in system preferences. When I try to open a session, apps just freeze and nothing happens, then I have to force quit. I googled many solutions, but no one has helped me.

    You must remove the serial number of your computer from your profile.

    Try a reboot.

    Make a backup using Time Machine or a cloning program, to ensure that data files can be recovered. Two backups are better than one.

    Try to set up another admin user account to see if the same problem persists. If back to my Mac is enabled in system preferences, the guest account will not work. The intention is to see if it is specific to an account or a system wide problem. This account can be deleted later.

    Isolate a problem by using a different user account

    If the problem is still there, try to start safe mode using your usual account.  Disconnect all devices except those necessary for the test. Shut down the computer and then put it up after a 10 second wait. Immediately after hearing the startup chime, hold down the SHIFT key and continue to hold it until the gray Apple icon and a progress bar appear. Startup is considerably slower than normal. This will reset some caches, forces a check for directory and disables all start-up and connection, among other things. When you restart normally, the initial restart may be slower than normal. If the system is operating normally, there may be 3rd party applications that pose a problem. Try to delete/disable the third-party applications after a reboot using the UN-Installer. For each disable/remove, you need to restart if you do them all at once.

  • "iPhone is disabled, connect to iTunes" AND "iTunes can not connect to the iPhone because it is locked with a password" error message on the phone and the computer! Help!

    So I recently had my password wrong too many times and my iPhone 4S locked out telling me "iPhone is disabled; Connect to iTunes'. And so I connected to iTunes and decided to restore my phone. I finished the process of restoration of the configuration of my phone, but ultimately, it was not even let me in the phone! Once AGAIN he said "iPhone is disabled; " Connect " to iTunes '. However, this time, this message appeared just when I turned on my phone with a black background. I didn't scan the screen for the error message is displayed (and there was no time to be shown). When I tried to connect to iTunes again as he asked, now it says "iTunes can not connect to the iPhone because it is locked with a password".

    So now, he said "iPhone is disabled; ' Connect to iTunes' on my iPhone 4S and ''iTunes can't connect to the iPhone because it is locked with a password ' on my computer. WHAT should I do?

    As described in step 2 of "Erase your device with iTunes" in this article, you will need to use the Recovery Mode.

    Recovery mode is described in this article as well.  You may try to go into recovery mode more than once to succeed.

  • I can not connect to Messages or FaceTime on my iPad

    I can't log into Messages or FaceTime on my iPad.

    I can connect in iCloud with my Apple but not Messagess or FaceTime.

    I've updated to 9.3.4.

    I recently received hundreds of emails from some Asian spammer all at once. I think that my message of account has been hacked or something. I tried to connect to remove them, but I can not connect now.

    I tried restarting and also did a reset a deletion and restoration, but nothing seems to work.

    I also rest my Apple ID several times with new passwords etc, but nothing works.

    SUggestions?

    Hello, Randy Burleson1,.

    Thank you for using communities of Apple Support.

    If I understand your message that you are not able to connect to iMessage or FaceTime on iPad Air. I like to use iMessage and FaceTime myself, so I want to help you as best I can to solve these issues. I recommend first of all, by ensuring that your Apple ID works correctly. To do this try logging on to appleid.apple.com from your browser.

    If you succeed, then on your iPhone go to settings and Messages. Scroll down and click on the section titled send / receive. If you are connected to the iMessage you will see the words Apple ID and email address. Type your address email Apple ID, click Disconnect.

    Once out of the faucet, use your Apple ID with iMessage and enter your e-mail address Apple ID and password.

    Repeat the same steps with FaceTime.

    If you receive error messages, please respond and let us know what you receive error messages.

    Best regards

  • Unable to send emails, SMPT can not connect to the server

    I use the latest version of the EL CAPTAIN 10.11.04, just updated software, and I can not send my emails is to show only SMTP error can not connect to the server.

    I can receive emails, but cannot send emails. I deleted the account and reinstalled it once again changed the SMTP Port 25, 465, 993 trying all of them.

    Please advice, or guide me what I am doing wrong, or what I can do to fix this error.

    Please take each of the following steps that you have already tried, tests after each of them. Back up all data before making any changes.

    Step 1

    In the Mail menu bar, select

    ▹ Connection Doctor window

    In the window that opens, double-click on behalf of SMTP (outgoing mail) problem. it. another window opens, displaying the list of all outgoing mail accounts. Choose the one that you clicked.

    Select the Advanced tab in the settings for the account and check the box marked

    Automatically detect and maintain the account settings

    If it is not already done.

    If there is more than one account of the problem, repeat. Close the window and save the changes.

    Step 2

    Open again the list of SMTP servers. Note the problem server settings, then click the sign button less to delete and confirm. Click on the sign more and recreate the account with the same settings.

    If you use Gmail, remove the account completely in the preferences panel accounts Internet and re-create it. The option "detect and maintain" must be selected in advanced settings for the incoming mail account.

    Messages will be again synchronized with the server automatically. Which can last for hours if the mailboxes are very large.

    Step 3

    Quit Mail runs. Launch the Keychain Access app and enter the name of the server of mail out in the search box. For example, if you use Gmail, enter

    SMTP.gmail.com

    Make a note of the password, and then delete the keychain items. The next time Mail connects to the server, it will prompt for the password. Enter and save the password in the keychain.

    Step 4

    If you use Gmail, sign in to your account on the site, and in the account settings, click the "Sign-in and security." There should be an option somewhere on the page to "allow applications that are less safe." Enable this option and save the change. Note: I don't use Gmail and I have not tested this solution myself. If it does not, either make you on Google user forums for help, stop trying to use Gmail with the e-mail, or just stop using Gmail altogether (strongly recommended).

    The mail server can use a form low, obsolete encryption for secure communications with customers. Recent versions of Mac OS X has changed the behavior of Mail and other applications so that they no longer tolerate low security.

    Log on to the e-mail account on the website and see if there is a security setting, you can change. I can't be more specific. Refer to the documentation of the service provider.

    If there is no adjustment, convince the upgrade of server securityserver administrator. He or she must do it anyway. Low security affects all customers, not only Mac users.

    Otherwise, you have all the right options to continue to use Mail with the service. You can disable SSL in the Advanced account settings, but that is very dangerous and may not work at all.

    You might be able to get a more flexible mail client, such as "Thunderbird", to accept the low security, or perhaps you can access the account via webmail.

    Ideally, you should switch to a provider of postal services better. You would not have this problem with a well-run service. The risk of weak SSL are known for a long time, and to competent server administrators have already taken the simple steps are sufficient to avoid these risks.
