Also I am getting timeout errors... Camera Initialized: EZB://192.168.178.60:24 @ 640x480

EZ-B v4 Camera Error: System.TimeoutException: Timeout für den Vorgang wurde überschritten. bei EZ_B.EZBv4Video.DwiGDUj2lU(Int32 , Object ) Camera Disabled

Can you please share the log for EZBPi from your Raspberry Pi console? Do you see any errors? Which Raspberry Pi are you using?

Most of the times I will just have to connect a few times and eventually it will work out and stay stable... I am running a Pi Zero W

But here is on example error the EZBPi logged...

================================================================= Got a SIGABRT while executing native code. This usually indicates a fatal error in the mono runtime or one of the native libraries used by your application.

Abgebrochen

Normally it gives me a few disconnects and logs something like this...

Raspberry EZBPi Version: 2019.3.29.0 Verbose logging is: False Serial port is: /dev/serial0 EZB: TCP Started on port 23 EZ-B Server started on TCP Port: 23 Camera: TCP Started on port 24 Camera Server started on TCP Port: 24 Press ESC to quit Camera: TCP Connection from: 192.168.178.61 Camera: TCP Connection from: 192.168.178.61 mmal: mmal_port_enable: vc.ril.camera:ctr:0(0xb14cb4a0) already enabled Camera disconnected on tty:1 Camera disconnected on tty:0 Camera: TCP Connection from: 192.168.178.61

Once I am connected the camera seems to stay stable!

Checkout the first line of the console where it prompts the version. You have an old EZBPi server. Try downloading the latest from Raspberry Pi page (https://synthiam.com/GettingStarted/Build-Robots/Raspberry-Pi-17681) and test again. Let me know how it goes.

Sweet, thanks a lot...I will try later today!!

Same thing...here is the error log...it quite long so I will put it to a new comment!
