Running into a pretty big issue on our setup.
We have a 4 node swarm running with NGINX reverse proxy and a simple web application.
For a few months now this has been running without a hitch but recently we began experiencing timouts, 503, 504 and 302 errors on a regular basis. There are no apparent issues shown in the logs, firewall rules are good, the stack has been redeployed multiple times and issues persist.
I have a feeling it is related to the overlay network?
Not sure what else to look into.
Also note that we have the same setup on a dev swarm and have not had this issue.
