What are the steps I need to do to setup MUC from a fresh install?

Usually mod_muc is already configured and enabled by default. Of course, if ejabberd is installed in a remote server, you will need to setup DNS for the MUC service, similar to what you may want to do for any other services that have their specific domain, like pubsub.example.org

You're showing us a screenshot where the first line has a variant, but your code will fail unless every line has a variant.

What is the output of this snippet?

Try giving the svg a very small negative margin-top, one or two pixels should do the trick. It should pull the shape up ever so slightly to bridge the gap.

Disclaimer: I never used pyejabberd, so I'll just give you some ideas to investigate.

I see your client attempts to connect to port 5443 with HTTP protocol. Looking at your ejabberd configuration, that has TLS enabled... so maybe it should be HTTPS? Or you can try to set "tls: false" in ejabberd.

Also, what kind of connection method does pyejabberd use to connect to ejabberd? XMPP (port 5222), or XMPP over BOSH (port 5443), or XMPP over WebSocket (port 5443, but a different URL path).

Maybe you should set in pyejabberd port 5222 and protocol xmpp, or something like that.

Check in ejabberd log files, if it receives the connection attempt. Try to login with a well-known XMPP client, so you learn how that looks in ejabberd log files (what messages it shows when login is successful), and compare that with your client.

I think you may be out of luck that the code was built against an assumption about a peculiarity that the Oracle Provider had around projecting null-able references that other providers like SQL Server do not share.

If you do end up accepting that you need to revisit your projections there are two options I know of. Either explicitly add the #null checks before projecting, or consider leveraging Automapper to handle the Projections /w ProjectTo as this does handle #null references, plus has the added bonus of making your Linq expressions a lot more compact. This would involve defining the mapping rules for Automapper to use. Depending on how consistent and predictable your entity vs. DTO naming conventions are, Automapper can resolve quite a bit by convention.

I place the credentials for user admin, but cannot log in.

Access of <<"admin">> from <<"44.44.55.55">> failed with error: <<"missing-server">>

You provided as account only "admin", and that is wrong.

As mentioned in https://docs.ejabberd.im/admin/guide/managing/#web-admin

So, you checked with "ejabberdctl registered_users" that the accounts are really registered. Then you tried with your custom XMPP client, connection is attempted (as seen in the log file), but fails with message "not-authorized".

Some ideas:

• A) Try enabling STARTTLS, but not require it: add this option to the 5222 listen: starttls: true
• B) Try login to ejabberd using a well-known Jabber/XMPP client, like Gajim, Psi, ... Does it work? then the problem is in your client. Doesn't work? then the problem is in ejabberd configuration

P5.js is not meant to be used outside of the browser. However, if you must, it can technically be made to work. I've posted an example below (which you can also view and run via my Repl.it project). But beware, there is no guarantee this will work for your use case. Just getting the canvas's image data to write to a file for this example was a humungous pain, so your mileage may vary.

index.js

three.js relies on your device's graphics card (GPU) and the WebGL API. Servers typically have neither, so I would expect performance to be worse — not better — unless you're spending a lot of money on the server. Libraries to emulate WebGL 1.0 on the server exist (see headless-gl) but I haven't seen stable libraries for the more modern web graphics APIs like WebGL 2.0 and WebGPU.

You might be able to improve time to First Contentful Paint, improving perceived performance, by caching an image of what the first frame rendered will show and displaying that while the three.js library loads. Perhaps SSR could help with that. But I wouldn't expect to stream realtime images from your server at 60fps in any case — rendering after the first frame is probably better done on the client.

Certain technologies backed by large teams (Google Stadia, GeForce Now) do manage to provide server-side realtime rendering, but this is probably not something you want to attempt on a next.js application with an emulated WebGL API.
