My MiaB setup has been basically rock solid for a very long time. However, now I seem to be having nginx issues. Very slow response in roundcube and in the admin screens. This leads to an eventual timeout. Restarting the server or just restarting nginx is enough to clear it.
This issue has been random ever since I migrated several gigs of email from closing out my free google workspaces accounts just a few months ago. The difference being I seem to have this issue every few days.
Any pointers at what I should be looking for?
