Hello All,
I am trying to upgrade Moodle 3.10.11 to Moodle 4.1, I put the system in maintenance mode and unzipped the files in the designated directory then copied the old config.php to the Moodle 4.1 and tried to access the UI to start the upgrade process, the system takes a couple of minutes then a message appears indicating that "stream timeout", I tried to visit the same page from the command line and the error appears there is "504 Gateway Timeout".
Have you faced any similar issues during Moodle upgrade and how did you solve it?
