Quick Summary: Constant ping timeouts in the last week, tried new servers with factory default settings, different VPS, different client OS/client, different residential ISP, different modem/router, different server versions. The only stable connection is from mobile networks.
In the last week or so all of my TS users seems to be experiencing the same issues myself included. Where we get disconnected every few minutes and then reconnect. All logs seem to point to the same.
I have a feeling that it’s due to ISP and or router/modem but it’s strange as well all have different set ups and different ISPs for the most part (note this is occurring with 5 users). What leads me to believe it’s ISP based is connecting to the server from my laptop while tethered to my phone network seems to provided a solid connection.
The issue I’m having is how do I proceed on resolving this and I’d also like more confirmation if my findings are correct as this is a strange issue to me.
Note: All testing below is with the new server and only one example connection failing. Logs otherwise are just regularly repeated. If anyone would like full logs I can provide them but again they’re the same messages repeated non stop.

(Based on the below it looks like the ISP or something inbetween the server and client is dropping the packets the server is sending to the client)

Servers Used:
Oracle VPS (Always Free Tier)
Amazon Lightsail (Cheapest Instance)
ISPs:
Rogers,
Bell
(Some other cheaper networks but they piggyback off the same networks, just mentioning this because it likely rules out router/modem related issues)
Server Info
TeamSpeak 3 Server 3.13.6
Linux 5.8.0-1034-oracle #35~20.04.2-Ubuntu
Based on the above I believe some UDP packets are being dropped from the server to the client. I’m not sure how to proceed on resolving this issue though. As normally I would contact my ISP if it were just me and move forward from there, but this is occurring with all of the people who connect to my server.
Any suggestions would be appreciated.
If there’s more specific information that I can provide that will be of use let me know.
Edit: I left myself connected to a licensed public server and confirmed this still occurs. At this point it’s definitely not the server so this post might fit better somewhere else. Granted it also might not be a teamspeak issue but it definitely seems to plague myself and my friends unfortunately.
