Actually I was able to make some progress, but not with Photon, not yet.
In the start, I was a full newbie and didn't know about how to use Caddy for reverse proxy. I have benchmarked myself trying to get an Alexandrite instance online(alexandrite.lemmy.com.tr). That was successful. Right now, the situation has came down to a 502 error for the Photon, help would be appreciated if I could DM you of the current situation on the bridged network and Caddyfile on matrix.
I want to finish these up and start to make Turkish translations for all lemmy-ui,alexandrite(finished) and photon.
