jatos 3.7.4 with nginx 502 Bad Gateway
We've got a new installation of jatos 3.7.4 on Ubuntu 20.04 with nginx and we keep getting intermittent but recurring 502 Bad Gateway errors.
I can usually get to the Bad Gateway if I log in as admin, go to the users tab, then back to the admin tab, and go back and forth a few times, although the error occurs at other times and for other users as well.
We were getting them a lot, but when I increased some timeouts in both nginx and jatos, and added some memory to the virtual machine, they stopped occurring so regularly but still occur.
We have an older jatos installation - 3.3.3 on ubuntu 16 - which wasn't exhibiting this behaviour.
We're kind of at our wits' end here, at the minute. Any ideas or pointers will be gratefully accepted.
