Losing Connection With high latency

Hi,
Ive already set the pingtimeout to 5000ms and Disconnect Timeout to 15000ms to try to avoid this. When I tunnel a player to Sweden and try to start a match, everytime after the player joins a room in matchmaking hes unable to send messages. When I test locally it works fine (even thought both players are using unity relay in both cases).
Does anyone have similar issues?
Can anybody from unity support help me?

Thanks,

Could be the different Unity Relay servers - i think there are geo-located, so a player in North America would have a different relay server from a European player. Maybe.

We do have region specific data centers, in this case it’s likely using our European data center in Frankfurt. If you’re able to talk to MatchMaker but not Relay (which is what you’re describing) it’s likely because the UDP packets are blocked by the network the other player is on. Some networks do this to prevent gaming or media streaming. Unfortunately there’s not much we can do at the moment to fix that at the moment, but we are working on fallback transports for situations like this.
