I believe I've fixed it.

A recent docker update no longer supports overriding hosts with hostnames. (I was telling mlmym that 'reddthat.com' is 'lemmy-ui'. Which would make it request directly to the lemmy-ui container rather than going back out to CF and back again.

(For others/if you want to know the nitty gritty). I was doing this:

    networks:
      lemmy_internal:
    extra_hosts:
      - "reddthat.com:lemmy-ui"

Which did actually work, but now it doesn't since I updated/installed docker compose v5.0.0. (Seems the correctly enforce the host:IP format now). So I had to do a work around.

    Thank you. It seems to be working now.

    I remember having a devil of a time trying to get mlmym and lemmy to talk to each other on my local system when I was poking around at trying to fix some issues in mlmym a few months back. (I should really get back to that at some point...) They had "https://" hard-coded in front of the domain name parameter -- and I didn't want to have to change the Go source code just to get a dev environment up. I ended up working around it by modifying my hosts file (to add a .INTERNAL domain), ran things under podman with host networking, configured Apache on the host to reverse proxy into both containers, and set up a self-signed cert that I had to rebuild into the mlmym docker (by copying in the appropriate crt files + running update-ca-certificates via the Dockerfile). In retrospect, I probably should've just modified the code...

    What was the workaround you had to implement to fix this one?

    I had to tell our main_nginx that it is "reddthat.com".

    services:
  proxy:
    image: docker.io/library/nginx
    ...etc...
    networks:
      default:
      lemmy_internal:
        aliases:
          - reddthat.com

    Now its: {user} -> CF -> {server_nginx} -> {frontend_nginx} -> mlmym => ((docker internal network)) -> {main_nginx} -> {{lemmy-ui/api}}
    Instead of: {user} -> CF -> {server_nginx} -> {frontend_nginx} -> mlmym => CF -> {main_nginx} -> {{lemmy-ui/api}}

    😥. I will fix it! I think because we are still going via nginx, it's still has to pass the go-away challenges, which it must be failing and thats why...

    Annnd, as we just moved I also only have key access to the server and I made all new keys and don't have one on my other devices yet. (A classic)

    Edit: nope, it's now attempting to connect over https to the container... I think I'll need to write a proper patch for it to allow for a override.
    It also looks dead in the water/feature complete. So I've moved to FSFs container. (https://github.com/Fedihosting-Foundation-Forks/mlmym).

    If I end up making a patch I'll upstream. (I'm surprised LW hasn't made one already)

    SORTED! Ended up patching it myself. Enjoy :D

    It's up and running again, but now it seems like pagination is broken. (Going to any page and clicking "Next" at the bottom returns a "there doesn't seem to be anything here" error.)

    Probably has to do with page=0 being in the URL for next page links?

    Edit: Looks like line 213 of state.go should be changed to q.Set("page", strconv.Itoa(p.Page+1)) -- I tagged you in the comment I made about it on the FHF repo too but not sure how well GitHub handles @ notifications.

    Thanks, patched and its page=2 now. (I wonder how LW never managed to see that... They must not be using that image...!

    Sweet. There's another issue open on the FHF repo where someone was questioning :latest vs :main tag so, yeah, there may be some mismatch between what they're running and what they think they are running / was originally documented...
