SOLVED!!!!!!!
Hi All,
I've been having issues with pangolin the last few weeks and i've tried some simple troubleshooting and also some extreme measures, but sill encountering the same issue.
I installed pangolin on a 2vCpu and 4gb ram hetzner vps. The newt is running on my truenas machine. I installed pangolin in March and it was running flawlessly for a couple of weeks. I then introduced two instances of technitium dns server. one on my vps and the other my truenas machine. the VPS retained its original dns settings and my aim here was to combine the two instances in a cluster and use it as the dns for my home network. Around this time I also installed Tailscale on truenas. A few days later I noticed that my services weren't resolving when trying access them remotely but would resolve no problem on my home wifi.
I assumed this was a technitium issue and I uninstalled technitium and still had the same issue. I then did a clean install of my vps in case it was an issue there and the issue still persisted. I then did a fresh install of truenas but the issue still persists. One of two things happens when I go to example1.mydomain.com when connected to my mobile network the service will either take about 2 minutes for the service to load or sometimes load almost immediately (i assume this is caching). I am at a complete loss what is happening here. if i try to access it on my home network I have no issues.
today I uninstalled tailscale because that was the only other change I had made at the time and that did not resolve the issue
Some other things i've tried
- pruned unused docker containers, networks and volumes that are not in use
- complete fresh install of VPS
- reinstall of truenas - reimported my pools after resetting the config
I can ping pangolin.mydomain.com and example1.mydomain.com on my home network and also from my mobile network and get a response time of between 43m and 68m.
Again if I try to access these services on my home network I can access the services no problem. when using a normal browser it bypasses the pangolin authentication screen and when using an incognito browser I am presented with the authentication screen. but once I try using my mobile carriers network it takes up to two minutes to get to the services.
Any help here would be great.
Edit: So I have managed to resolve the issue. It was something to do with my domain. after sorting out the issue with letsencrypt I described below I still couldn't access my services remotely, even though the logs all looked ok. I bought a new domain as a total swing from the fences type approach. reinstalled pangolin on my vps, connected the newt and boom everything worked again no problems at all. I'm sure whatever caused it was initially a user error. As the old saying goes "I know enough to be dangerous"
