element-web: Cannot join room from matrix.to link, "No known servers"

Description

I tried to click on the link in this message and could not join the room this was pointing to:

https://matrix.to/#/!xYvNcQPhnkrdUmYczI:matrix.org/$DJYCtRsqEio-s577yqTZya4EfSnfenU_QIJZ6LYFzK4?via=matrix.org&via=feneas.org&via=maunium.net

This was the link I couldn’t follow: https://matrix.to/#/!yjVgJUsMLYLAONsoii:jki.re/$ABrOfGufg7k0jRLV0MnVLUnD28BYWMFy51hai0SZunU?via=jki.re&via=matrix.org&via=kde.org

@anoadragon453 I can still reproduce the original issue, i.e. going via https://matrix.to/#/!yjVgJUsMLYLAONsoii:jki.re/$ABrOfGufg7k0jRLV0MnVLUnD28BYWMFy51hai0SZunU?via=jki.re&via=matrix.org&via=kde.org I eventually end up with the following error message from element-desktop:

MatrixError: [404] Can’t join remote room because no servers that are in the room have been provided. (https://matrix.bubu1.eu/_matrix/client/r0/join/!yjVgJUsMLYLAONsoii%3Ajki.re)

The network request sent is:

I think the issue here is that element interposes the “can’t load timeline position” popup for me (as noted above) and at that point has lost the via parameters.

I’ll send a rageshake. (Edit: sent)

Edit 2: No change with Element version: 1.11.20 btw. (the latest I currently get from my distro)

@JeanPaulLucien the room directory availability has nothing to do with being able to join rooms via this server. Once again, please stop spreading false information here.
