Error fetching and sending emails

[marianmurin]

I have a problem after installing grive app to fetch and receive emails in Freescout. I am using Gsuite email for helpdesk.

Fetch errors: Error: imap_open(): Couldn't open stream {imap.gmail.com:993/imap/novalidate-cert/ssl}. Retrying PLAIN authentication after [AUTHENTICATIONFAILED] Invalid credentials (Failure); Retrying PLAIN authentication after [AUTHENTICATIONFAILED] Invalid credentials (Failure); Can not authenticate to IMAP server: [AUTHENTICATIONFAILED] Invalid credentials (Failure); File: /www/wwwroot/helpdesk.improve.sk/overrides/webklex/laravel-imap/src/IMAP/Client.php (230)

Send errors: Failed to authenticate on SMTP server with username "support@improve.sk" using 3 possible authenticators. Authenticator LOGIN returned Swift_TransportException: Expected response code 235 but got code "535", with message "535-5.7.8 Username and Password not accepted.

I have already checked that and tried almost everything, but with no luck. I have even talk 2 hours with Google with the same result. They talk about some certificate which is needed to communicate with Gmail server, but I did n ot find anything about this server stuff on the forum and our knowledgebase.

Could tbis be related with OpenSSL ON MY VPs?

[freescout-helpdesk]

Fetching and sending errors are indicating that your credentials were not accepted. It means your server is able to connect and OpenSSL is not a problem. Are you using App Passwords?

[marianmurin]

Yes, I am using App Password 2FA is turned ON. I am attaching screebshot from connection setting for fetching and sending.

Sometimes, for whatever reason, fetching emails failed, and error below

Error fetching email | Error: connection setup failed; File: .. ... /vendor/webklex/php-imap/src/Client.php (391)

I also sometimes have this issue.

Whenever this error happens, system shows 2 cron jobs are running and one process shall be killed.

Whenever 2 cron jobs are running, server CPU utilization goes to 100%.

Questions:

1. How to prevent the error from happening? (It happens a few times a week. I have multiple mailboxes and frequency is 1 min each mailbox, so I would say it is an infrequent error)
2. Where to get the specific error logs? e.g.: which email fetching produced the error, and why? (I checked Manage->log->fetch email, but no useful information)
3. When it happens, how to kill the process automatically?

Thanks!

Try to change App Password. Are you using GSuite or you've somehow set a custom domain (support@improve.sk) for a regular Gmail?

[marianmurin]

I have already changed App password, but It does not help. 2FA is trun ON and I am using paid GSuite.

[freescout-helpdesk]

We don't have any other ideas.
