I often get the problem/error that my osbotclient just vanishes, it happens once every couple hours or so, any idea how to fix this or what the problem is?

I have seen this happen for many users in the past few days, but I'm going to hint that maybe it's CPU related?

What are your specs? 

I had the same thing. I think it occurs when you have a bad connection to the osbot server. When i was botting in my with my laptop in my room ( got a bad connection there) it just closes after a around 20-30 minutes. Now I'm in my living room where my connection is way better and this issue doesn't seem to happen anymore. 

 

It could also be your firewall blocking some connection with the osbot server but it's just a guess.

 

Hope this helps you.

I've had it while at the pc watching a youtube video has nothing to do with connection.

it happens when u have a bad internet connection happend to me once or twice 

All people about "bad internet connection" i have one of the best internet connections so it'd be strange if this was the actual reason.

It's a bug in the client itself
