Cannot join room from matrix.to link, "No known servers"

[Bubu]

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

I've been recently seeing these links not working when you click them (leading to No Known Servers), however if you then add the via parameters manually to the URL and then try to join again it works.

Seems like Riot regressed at some point in extracting them from the URL when clicked?

Any progress on this? Experiencing the same issues currently with various matrix.to links (up-to-date Debian riot-desktop package).

Can you confirm that when clicking the link, your browser is making a POST /_matrix/client/r0/join/{roomIdOrAlias} request without any server_name query parameters included?

If they are there and you're getting No known servers, then this is a server issue.

If you find this issue because you can't figure out how to open a room link in element-desktop, look at #12879 .

@alexrollin: this is the repository for element-web, android issues aren't tracked here.

Is there any progress or any more info on this? I'm experiencing this when I'm trying to open a room from another server.
