Yep, I think it maybe a network issue as well. I'll check the connections.
Thanks Eugen:)

Hi,
my first guess would be a network issue. Double-check your connections
and make sure the network setup works as expected. Check syslogs,
dmesg, switches etc. for hints that a network interruption may have
occured.
Regards,
Eugen
