I reinstalled and am getting the same socket error. Everything else works fine. I did some more digging and seem to be having a very similar issue to these two posts: https://forum.iredmail.org/topic20529-c … rvice.html
https://forum.iredmail.org/topic20702-c … ainer.html

I just don't understand or know some of the stuff used in these and am looking for some guidance. It appears to be some sort of issue related to being an lxc container and the permissions. Not sure what to set the permissions to for this to work. I also tried to run a privileged lxc instead but i had trouble getting that started with ubutnu.

Not sure what you changed, but i suppose iredadmin works after iRedMail installation?

I was never able to access the iredadmin panel at any point after install. It was a fresh install and I tried twice with the same result. I'm going to try a fresh reinstall on a new lxc.

Further update, I've done some more troubleshooting and have identified that the error is not with the proxy but with the iredadmin service. I am unable to access the panel at the local level with the ip address and /iredadmin or the ip with port 7791 and /iredadmin. I've attached the status of iredadmin that I ran in the command prompt with some sort of failure I don't understand. Any ideas

Anything helps!!

Note: I tried to change the port from 7791 to something else to try if that was the issue, and since changing it to that (it not working) then changing back to 7791 there's an extra line on the bottom with mail systemd.

To add to this, I logged in to test the server under the postmaster account and am able to send and receive email. My issue is just a proxy issue it appears

I recently setup a new iredmail server. Since i run a few servers that require web based stuff i use Nginx Reverse Proxy (NPM) for my web port proxies. During the setup process ive run into the problem of not being able to accsess the admin panel. When I go to it i get an error "502 Bad Gateway" and underneath it says "nginx". However, when i go to the mail login the roundcube pops up as normal. Inside NPM i have port forwarding of https 443 to both mail.mydomain.net and mydomain.net, with SSL certs in there (i did not do the certs with certbot since it wouldnt work for some reason). Whenever I have tried http and port 80 I get a to many ridirects error on the google side. Not sure what do to from here there is little info on this from what ive found.

Any help is appriciated.

Note: all NPM proxies have websockes and common expoit blocks on, and SSL is forced with HTTP/2 support and HSTS enabled.
