@julian It is interesting to see long form content in the Fediverse. I'm still not used to it.

Pretty cool.

Good Idea to give federation issues a separate topic. I have made the changes on your list resulting in posts and chat messages coming out of the forum, but still nothing can be pulled into it, no matter how many people or sites I follow or try to follow. Funny, I couldn't find how to access AP users that I am apparently following other than by re-following them. They are not listed among local forum users.

@julian Can you give me some ideas what to do next?

@Jakub-Urbanowicz can you give me a example of something that cannot be pulled in?

Also run the forum under dev mode (./nodebb dev) for some additional logging around ActivityPub.

@julian Some of the users I am following (or so it reads on each user's page):

@ju@pol.social (Mastodon)
@kodmalopolskie@soc.citizen4.eu (Friendica)
@oko_press@101010.pl
@kravietz@agora.echelon.pl
@julian@community.nodebb.org
https://community.nodebb.org/post/102755 – imported by link (can't post remotely)

Nothing special happens when running dev mode. Just some plugin incompatibilities get printed:

2025-02-15T05:36:53.950Z [4567/3360] - warn: [plugins/load] The following plugins may not be compatible with your version of NodeBB. This may cause unintended behaviour or crashing. In the event of an unresponsive NodeBB caused by this plugin, run ./nodebb reset -p PLUGINNAME to disable it.

I've been able to npm unl / npm i nodebb-theme-harmony, but I wasn't successful with plugin-composer-default or plugin-custom-pages, so I gave up on the rest of them. Every time I ran npm I saw a warning that my nodejs was outside requirements (probably too new, if I got it right).

In trying to fix things I have made changes to nginx reverse proxy configuration, but I seem to have made things even worse, which is not a bad thing, because in that may lie the solution.
I'll be happy to provide log and config files by a secure channel of your choosing.

@julian
Here you are some AP errors from a few days ago, before I made any changes.

My forum.n66.pl-proxy.conf is now very similar to official recommendations and doesn't seem to have any effect on AP following/sharing capabilities.
I am unaware of server tweaks to facilitate AP following/sharing.

@Jakub-Urbanowicz your ActivityPub user is resolving, but the URLs are incorrect.

Please update your config.json so that it properly reflects your site's url, it should be https://forum.n66.pl, with the https

Hi! I am also having federation issues on a fresh install of 4.0.3. For example, I can not see the content of all the posts here including the original post. I think I see the content of around half of the posts. I tried to reply on another post on community.nodebb.org, but after ten minutes it is still not visible at community.nodebb.org.

Ironically, I am not sure this reply will reach community.nodebb.org either.

@reynir OK great! This one went through. However, I still only see about half of the posts.

(Finally, sorry for barging in on your topic - perhaps we can fork the topic somehow)

@reynir@forum.fedi.dk the post content being blank issue might be an unrelated bug. I'm still trying to figure out that one.

@julian@community.nodebb.org thanks for the reply! Is there a tracking issue I can subscribe to?

(I am having a lot of fun with our new NodeBB instance btw!)

@reynir@forum.fedi.dk there wasn't, so I added one:

Unicorn! · GitHub

(github.com)

@julian That and upgrading to 4.0.4 helped a little – at least direct messages are coming through, but following still not working in either direction. Following seems to be set up correctly and confirmed on both the forum and other AP instances. Testing with Friendica and Mastodon. Only the messages are stopped somewhere.

@julian I am now unable to import threads using the search area. It worked a few days ago (before 4.0.4) and maybe before changing http to https in config.json. Now I can only follow users without actually following their content (no following is operational). While importing threads worked, it was still useless, because I couldn't join in on conversations.
Yesterday I experimented with different proxy_pass values in my nginx proxy.conf file:

• proxy_pass http://forum_n66_pl; – original configuration
• proxy_pass http://127.0.0.1:4567; – no effect on AP behaviour, nodebb's admin privileges affected
• proxy_pass https://forum_n66_pl; – resulted in a "Bad Gateway" error.
  I attach the recent log file: https://u.pcloud.link/publink/show?code=XZun2L5Zy2PaNwGjuh72kxKbh6Wl9jEb4FmX

Please tell me you know how to fix it.

@Jakub-Urbanowicz http://forum_n66_pl this suggests there's an upstream block.

Can you paste your entire nginx config?

@julian just a moment; it's a bit complex, because configuration is divided into several files.

@julian Please find attached a summary of my nginx settings.
The back-end installation of NodeBB was done manually in a home directory, while the reverse proxy is part of on automated server solution called Webinoly. It is typically used for self-hosting WordPress, but not only. It worked pretty well before the advent of Federation capabilities, so I wasn't bothered. I just uncommented some proxy headers in /etc/nginx/apps.d/forum.n66.pl-proxy.conf and added "X-NginX-Proxy true" as per documentation. Mongodb (7.0) is provided from a deb repository as is nodejs.
I'm not sure why the web root directory as mentioned in /etc/nginx/sites-available/forum.n66.pl does not exist (root /var/www/forum.n66.pl/htdocs). I don't even have /var/www/forum.n66.pl/.
Thank you for helping me.

@Jakub-Urbanowicz whatever your nginx config, if it was working before, it should not require any changes to support federation.

I would revert back to a working config if you're seeing issues with regular usage of NodeBB. Otherwise if the site is loading fine then tweaking nginx (probably) won't fix anything and the problem likely lies elsewhere.

I will look into your configs tomorrow.
