Greetings, not really sure how to troubleshoot my problem so any help is appreciated. I had letsencrypt set up with my registered domain and reverse proxies working with 3 docker containers (calibre-web is one). Sometime in the past couple days it stopped working. I am getting a site cannot be reached error and port 443 is no longer showing open for me. Checking the letsencrypt logs I see this:
Repeated endlessly. I glanced at my pihole and see that my unraid server is spamming ocsp.int-x3.letsencrypt.org about 2500 times every 10 minutes since yesterday. That's about 4 times a second. Some googling on that error essentially tells me to ignore it and letsencrypt still works fine.
My port forwarding has not changed, I have not touched the configs for letsencrypt, etc. My best guess is something stopped nginx from serving up the sites and thus the ports are not showing open. I am not sure where else to look for how to resolve this issue? Thanks.
Edit:
Found the problem, there was a typo aka user error in one of the conf files. I had replaced http with $upstream_proto in one of the conf files and had a typo such that the p from http was still there. Sorry for the distraction!
