Hello all!
First of all, thank you for the help I have already received! I see the light in the end of the tunnel... i just hope it's not a train!
So, my Lemmy server IS up and running, but the lemmy-ui seems to be incorrectly configured in nginx.
The setup:
lemmy.mindoki.com is redirected with an A redirect to my static IP, where my ISP-Router box forwards port 80 and 443 over TCP to my Lemmy PC.
In the Lemmy PC is a fresh Linux mint with a Lemmy Docker install.
.
Some things works:
http://0.0.0.0:1236/pictrs/image/730840b6-d6ec-4a40-8668-36b89c6c1d33.png => Gets the image
https://lemmy.mindoki.com/pictrs/image/730840b6-d6ec-4a40-8668-36b89c6c1d33.png => Gets the image
curl “https://lemmy.mindoki.com/api/v3/community/list?sort=Hot&Limit=1” => Works
.
Some don't:
https://0.0.0.0/ => Server error
https://lemmy.mindoki.com/ => Server error
.
RoundSparrow (I don't know how to link users, sorry!) helped me out (here: https://lemmy.ml/comment/1715961) a bunch and suggested trying a smarthphone client, and lo and behold, it Works!
So it seems, as RoundSparrow figured out, my nginx configuration is not correct comming to routing ssh to my lemmy-ui docker.
I have spent the evening tinkering like a cave-man but to no avail, so I'm asking you knowledgeable people out there for help, and any help greatly appreciated!
Thanks again!
