hello, I have a server for more than 1 year, and about 5 months ago I have a problem with my server, 
80% of the players are being kicked from my server by " Kicked: Steam: InvalidAuthSession " they stay
at most 1 hour playing and are kicked. Before this problem my server had around 30 players, and nowadays it's no more than 10 because of this problem.
I already tried to talk to my internet provider, they did several tests and adjustments and it didn't improve.

I was wondering if there is a server setting that increases the data response timeout to see if it improves.
Please help me !!!!!!!!
