Unable to open Updates & Upgrades on Plesk for Linux: ERR_CONNECTION_TIMED_OUT

    I know that we always want to think it's a firewall issue, which at times it is; mostly on new servers. However, I manage 15 servers that utilize Plesk and it used to only occur infrequently on older versions that would just require removing the lock file. In recent updates, this issue has been happening more frequently to the point I handle most changes via CLI just to avoid the headache. Naturally, this is unfair for some not-so-savvy tech users.

    Hello, @Daerik Khan!

    There indeed can be some issues when Web Installer updates itself and the update require some additional time and failing with timeout because it was not able to update itself in time.

    In such case, next try from web interface after a couple of minutes should help.
