Access to Journal Managers, Site Administrators and can't send email in OJS v 2.4.6 takes a long time

For 1 month, my journal has problems with access to journal managers, site administration, and cannot send any e-mail through OJS. So far I have never made changes, both on the server, and on the OJS application. I tried to find out what made this happen, but I did not understand. Is this picture that I attach is the cause of access disrupted?
error

And also here, i can’t understand what happend.

The long-running t.php script is unfamiliar to me. Do you have a plugin or addon which might account for account for this script?

The javascript notices are unlikely to relate to problems with email in OJS 2.4.x. Try looking in your PHP error log for more details.

Here the error.log for long running Administrator pages and journal manager:

The errors here indicate that your server can’t connect to gmail over port 465. Check with your hosting provider or system administrator to see whether there is a firewall or other restriction on outbound traffic from your server.
