Hello!
Has anyone had issues with their designer timing out every once in a while? I've been using Ignition for a little over a year now, and since migrating our service to the cloud we've been having some random timeouts.
I've spent a lot of time trying to figure out if someone else here had a similar issue, but I haven't found anything that helped so far.
Our current setup is a Rocky Linux VM (8 CPU, 32GB RAM) running our Gateway, and another Rocky Linux VM (1 CPU, 2 GB RAM) running our Caddy Server as a reverse proxy/SSL provider. I've some hours monitoring the reverse proxy machine to see if there was a peak in it's usage, but the only peak it shows is when I open Cockpit.
The only thing I can imagine of that could cause an issue related to connection would be our bandwidth, that is limited to 50MB, but the traffic observed on Cockpit is minuscule compared to said limits.
Oh, I forgot to add the message that I get in the Designer Console:
