For several days, I have been trying to set up NextCloud on testing rig first to make sure it works then I would set it up on my main server. I have been following a series of tutorials from Spaceinvader One (See Below) and I have been following word for word except for the parameters that correspond to me. When I tried to make sure the Reverse Proxy is working after doing the port forwarding in my router, I should see the Swag Instance screen, but instead I'm getting Cloudflare error 522. I followed the tips on Cloudflare's community page so far with no luck. Then I saw a similar post from a few years ago with a different reverse proxy and someone suggested going under the management access and changing the HTTP & HTTPS ports and adding them into the router settings to if that helped. I tried that and all I could bring up was Unraid login screen. I switched them back and now I'm back to Error 522.
Please if anyone can help, it would be greatly appreciated. On a scale 1 thru 10 of how much I know Unraid, I'm basically 2-3 (newbie). The only thing I have working properly is Plex for my library.
