reconnect

each reconnect generates the same log.

Library version: 2.2.2
Atem firmware: 8.5

I am not sure if firmware was upgraded on the devices since the time when it was working.

Seems that the issue appears when communication goes through VPN connection.
I tried to run the same code from pc located at that network where Atem switch is and it works without errors.

That makes sense. I can't remember which way it is running anymore, but there are pings being sent to detect for timeouts/disconnects.
In general the protocol is rather picky about latency and if the client/atem doesnt respond within a few hundred ms the connection will be closed and trigger a reconnect.

There might be something we can do on our side to minimise the risk of this, but a lot of this is enforced by the atem, so I am not confident.

Sometimes I have had issues with even the official app over a vpn, and other times not.
