service sapdp80 timed out when starting GUI

[Former Member]

Clients of my company access our SAP server by VPN. One new client met a problem, they can access VPN, however, when they start SAP GUI, there comes an error"connection to host xx.xx.xx.xx, service sapdp80 request timed out", in its detail, "time: Fri...;component NI; Release 640; Version 37; Module nixxi_r.cpp;line 1070;Method NiPconnect;Return code 12;Counter 1".

And its so weird that all other clients are ok with both VPN connection and SAP GUI log on. I searched SAP note for this error but found no result, and I came here for your precious working experience. Has anyone met this error before?

Looking forward to your help.

Hello. After VPN connection are up , are this client able to ping the SAP server or other servers in your LAN ? The

"ipconfig /all" shows correct settings? Are the "hosts" and "services" adapt properly? Are this new client able to coonect any from other sapservers? Regards

Our client can't ping to SAP server, while the rest of the client can. It seem like it's the problem while connecting, but the problem is to find the reason for the connection failure.

Yes it's the connecting problem. Are you able to phisicaly see the client PC , and check the VPN and TCP\IP settings? May be it's some firewall or antivirus software are installed on clients side. You need to analyse all, for example after VPN connection are established the "ipconfig /all" should show parameters with which user has got in your network to. Regards.
