New to MikroTik, just swapped from OpenWRT. Hosted Nextcloud no longer connects

RouterOS Beginner Basics

Hello all, new here and probably overlooking something simple…

My issue is I just swapped out my OpenWRT router with a MikroTik (hAP ax3) and forwarded all the correct ports to hit my Nextcloud (docker AIO) server, using the same subnet and internal IP as before. Now when trying to browse to my public URL i’m getting a “Refused to connect” even though it was connecting fine just before swapping. The only indication of an error I’m getting from the Nextcloud side is this on the Apache container-


INF ts=1696998816.6505415 msg=using provided configuration config_file=/tmp/Caddyfile config_adapter=
INF ts=1696998816.6556993 msg=failed to sufficiently increase receive buffer size (was: 208 kiB, wanted: 2048 kiB, got: 416 kiB). See > https://github.com/quic-go/quic-go/wiki/UDP-Buffer-Sizes > for details.

I feel like this isn’t a Nextcloud config issue since it was working fine prior to swapping, but I could/likely be wrong. Any help in pointing me in the right direction is much appreciated! And thank you in advance!!

Out of curiousity I browsed to the http address of my Nextcloud server and hit the mikrotik router login page! Not what i was expecting and is likely my fault. I picked this up wanting to learn more about RouterOS and it’s clear I still have a lot to learn!

So it appears my router is taking over port 80 and 443 which would explain the conflict with my Nextcloud server.

UPDATE: Found that I can connect to the Nextcloud server just fine from outside the network. I did restrict access to the router to allow only from my internal subnet and changed the default service ports. Getting closer…

UPDATE 2: Got it, and was so simple, needed to add a DNS entry :::facepalm:::
