Hi Ventsislav,
3300 seems to be open on the ERP instance provisioned from CAL.
telnet 52.X.158.Y 3300
Trying 52.X.158.Y...
Connected to ec2-52-X-158-Y.compute-1.amazonaws.com.
Escape character is '^]'.
However, connecting from the cloud connector does not work. Same error that the Internal Host cannot be reached (timeout)
Regards
Suneet
