CCam server stops after an hour while using blackhole 1.75 on vu+ultimo

Hello guys.
I have just started with blackhole 1.75 on my vu+ultimo. I am using oscam3841/CCam213 with jsc cart. I am doing this all on a CCam server, but unfortunately, server runs for sometime, say about an hour and then stops.
I opened the pluggins-CCam info V1.3c and clicked on one of the two options client or server.
On doing so, I am met with an error on the screen. The error says:

BH Message
Error reading webpage!
I simply don’t know what to do with this error. If anyone has any idea, please do let me know.
I'll be really thankful.
Regards.
