Kicked with: server_went_down

[andreasdc]

I'm often getting kicked after connecting to the server with server_went_down message, but there are no errors on spigot or bungee.

[electronicboy]

You'd need to work out why the connection disappeared, there is nothing here to suggest that this is a waterfall issue, and this is not the place for support

Kick reason is from proxy, so how to analyze it?

[electronicboy]

Kick reason is from the proxy because the server lost connection and thus, the proxy no longer having somewhere to connect you to, kicked you from the proxy

There is often logs when this stuff happens, but, not always, you'll have to try to deduce what caused it

I only have 'disconnected' as reason in the logs, no errors or anything.

What's the fix?

[electronicboy]

There is no fix atm, don't have duplicate team names across servers, basically

[andreasdc]

Isn't it creating memory leak for clients?

[andreasdc]

There is no fix atm, don't have duplicate team names across servers, basically

Also shouldn't it just be overriden, as you can't do much with scoreboards from another server?

[electronicboy]

It's not creating a leak, there is generally a race condition within the logic due to how server switches occur which makes it much harder to solve than just "overriding", please read the linked issue

1st server didn't have any scoreboards, should it happen in that way?

[andreasdc]

@electronicboy no way that this would happen again, something is more messed up than that.

[electronicboy]

This is not the place for a back and forth discussion, no need to spam peoples emails; You clearly have something using scoreboards, and the name doesn't look unique, so, likely some plugin on both is causing duplicate names across server instances

Shouldn't it clear scoreboard objectives when switching the server?

#737 (comment)

So If I create objective with name I can't use it anymore on any server during the same proxy connection?

[electronicboy]

Yes.

[andreasdc]

Yes.

Well that's a litte bit problematic, right? 🚀 I had the same names on every server and I didn't have this problem earlier.

[Janmm14]

Yes.

Doesn't your "yes" mean that vanilla scoreboards will cause this problem once you enter the same server for the 2nd time in your proxy connection?

[electronicboy]

Yes, you can't have duplicate team names across servers without it breaking, this is a long standing bungeecord issue, hence the already opened issue for this; resolving this however is a PITA because aspects of this fall into the API, of which any fix for this is potentially going to introduce race conditions or inconsistencies with the API

[ColorsASD]

I had a similar problem on 1.19.1 and 1.19.2. The connection with the server was continuously disconnected with the message "server went down". Although I did not experience an error line.

BungeePackFix update solved the problem, I hope I can help someone with this as well.
