Describe the problem

I had a coordinator server on AWS Virginia and an exit node in Singapore.

When I tried to connect using Windows, I randomly encountered the following conditions:

Sometimes, there was always a request timeout to the internet.
Sometimes, I got a ping of >400ms (even though my public IP showed Singapore, the latency should have been only ~10ms).
Sometimes, I got a ping of 10ms, with my public IP correctly showing Singapore.
When I had a 10ms ping and tried to disconnect and reconnect, the connection failed and seemed to hang

I have already searched through the issues for a solution but still have no clue.
I captured logs using netbird -A debug for 2 minutes and have attached them.
I have already opened all inbound traffic in the AWS security group.

netbird.debug.1914716158.zip

Expected behavior

Got a Singapore IP address with a 10ms ping, and the connection no longer hangs when disconnecting and reconnecting
