[NEED HELP] Multiplayer server listed twice - causes glitchy play

When I go to the Multiplayer window one of the servers which I often play on has a double listing for the last few weeks.  Specifically, TheRegulars server.  It's a listing for the same server appearing twice.  Everything is identical between the two except the ping is slightly different (yes, same players, same map, etc. it's the same server).  When I try to play it, all seems fine, but every minute or two it glitches and I glitch through a wall or stutter etc.  Anyway to fix this?  I get the feeling I need to delete the data from some folder/file containing the server info to allow it to reset or something.

Darn, nobody knows the answer to this problem?

Man... not much point in these forums for getting help...

QuakeNet: #xonotic

Try there.

I'll try.  It disappeared for about a week, so I thought it fixed itself.  Then it came back again.

Now, 90% of the servers are listed twice. Updating to newest versions has never fixed the problem. I tried resetting to the default master servers. Tried may different things over the years to no avail.

It seems the Xonotic client is querying the master servers (or individual game servers) twice and this causes every (or nearly every) server to appear duplicated, especially established/older ones.

Good to see that you're still playing!

This is a long-standing issue with IPv6 server IPs being duplicate entries, a bug report is tracking it here: https://gitlab.com/xonotic/xonotic-data....ssues/1457
As far as I'm aware the only workaround currently is to disable IPv6 in your operating system's network settings, so you'll only see IPv4 entries. You shouldn't encounter any issues doing so, as the internet will likely be relying on IPv4 addresses for the foreseeable future.
