After setting up the server, occasionally it would be unable to connect to the the server. e.g. even the web designer gives a 502 bad gateway error. From the docker logs it seems that the SSL cert is invalid?
Some of the nginx logs:

I run renew.sh and wait for a few minutes and it seems to be normal. Does anyone have this similar problem before?
