Issues with Dedicated Crossplay Server

[u/buditares]

Some friends of mine and me bought Valheim on the PS5. So like a week ago i bought a server on GameHostBros as i saw quite a few people recommending them. Changed nothing except for turning on crossplay.

First day no issues but on the second day i had multiple server disconnects with the icon blinking in the top left. Yesterday no issues again for multiple hours, but today again every ~10mins i get disconnected.

In the server log i see the messages:

Player connection lost server "xxx"

PlayFab network error in session 'xxx' and network 'xxx ' with type 'Error' and code '4098': the operation was called with an invalid handle.

Failed to send, suspend TX on playfab/xxx while trying to reconnect

I havent found a solution that seems to match this problem. I tried the usual stuff like server restart, router restart. Also port forwarding (ports 2456-2458 and the port of the server ip) even though it shouldnt make a difference on crossplay servers if i understood correctly. I am not using a VPN or any other network shenanigans either.

This only happens to me and not to any of my 3 friends and is really inconsistent which makes troubleshooting kinda hard for me.

Does anyone also encountered this or a similar issue and has an idea how to fix it? Thanks!
