Dedicated Server Disconnecting Players Every 10 or so Minutes After Latest Patch

As the title says, our G-Portal hosted dedicated server has been disconnecting all players every 10 or so minutes since the latest patch. We all get the new D/C icon flashing in the top left then a few seconds later, everyone is disconnected. Server is still up as we just reconnect right after it happens.

No mods on this server. Completely and 100% vanilla Valheim. Working completely fine before today's patch (0.148.6)

I have restarted the server to see if that would fix it and nothing. Autoupdates on the server are turned on and the server is updated.
