Hi Sap Club Admin,I can access sap1.yok.com.cn from home, but when trying in office, the connection timed out and refused. I can ping to to sap1.yok.com.cn and my network support did a trace from end and end, there was no problem. But, I am unable to connect from sap logon on office network. The configuration is correct, since it works perfectly at home.The network support would like to know which port I should connect to for this server. Are you able to help?Thanks.
