unable to add yahoo/google mail accounts

since upgrading to El Capitan I'm unable to add any yahoo or google account ...

when trying to add an account (gmail or yahoo) into mail an error message pops up stating:

Connection Insecure

Failed to verify the server certificate. This could be because of your network configuration or your proxy settings.

when trying to access the accounts via web browser all goes ok, so there’s no network/internet connection or proxy issues. In fact, I'm using no proxy whatsoever.

The error is the same if trying to add the accounts using mail or the internet accounts system preference ... I imagine is something related to OAuth since for any of these two providers that is the authentication method used to configure them

any help would be greatly appreciated

Been battling with this for quite some time. Removing all certificates didi not help, neither did removing the entire keychain.

It was AdGuard, even though it wasn't showing as a blocked page or anything - disabling AdGuard allowed me to add the account and it still works after re enabling.

Found the fix for this.

there're two verisign certs with a red mark "This certificate was signed by an untrusted issuer" in the Login/Certificates container in the keychain. You need to delete them, once removed the Connection Insecure message is gone and will be able to add the accounts.

While I did find expired certs, and deleted them, they were not pertinent to the email servers involved in my problem.

I have multiple accounts to Google/Gmail and only one is experiencing this problem.

Hi

be sure to look for Verisign certificates as in the image below .. check all of them for having the green check mark -- the ones to delete show a red x stating "This certificate was signed by an untrusted issuer" don't recall exactly but think mines were still valid (not expired)

This is a problem with Keychain. Delete ~/Library/Keychains/* and then you can add the account. Feel free to restore thereafter.

I have the same problem trying to add a Yahoo account to mail. I've looked at all the Verisign certs and all have the green check mark and have expiration dates in the future. I'm new at working resolving issues with Apples OS (I have El Capitan installed via update from Yosemite), and don't know how to delete the ~/Library/Keychains/* you mentioned, nor how to restore it after. Can someone tell me how to resolve this in a way that won't have me destroying my OS installation?

This turned out to be an expired/revoked Verizign cert for me as well.

You have to cycle through each of the Verisign certs to find out which one is bad and delete it... you may also have to reboot or restart Mail.

Hi there. I should have spent a bit more time explaining that this is a certificate in keychain. However, you can go fishing and hopefully find the bad cert. But, this will take some time and/or a bit of luck. In my case, I removed all the bad certs that had expired or was revoked for whatever reason, and that did not work for me.

Since I have everything I care about in iCloud Keychain, I removed System Preferences > iCloud > Keychain, deleted ~/Library/Keychains/*, rebooted and then added my Google account accordingly. I then added System Preferences > iCloud > Keychain back.

I have a similar problem but it only applies to a google .edu account. My personal gmail account was added just fine. Overtime I try to add my .edu google account to internet accounts in system preferences or mail's preferences I receive the following error...

Authentication Failed

Failed to authenticate with Google, please try again later.

This also freezes System Preferences requiring a force quit.

All in all El Capitan won't add my google account. Anyone know how to get this to work?

Hi .. i think your issue is slightly different to the one I was facing when opening this thread .. so maybe the solution posted will not be applicable to you.
