SAP router host did not respond

[former_member300702]

Hi,

I have tried to open SAP OSS connection, When I tried for first time the connection opened but after some time the connection cancelled.

Again I tried to open the connection but I am getting "Host did not respond" message. Also i Have did connection test for SAPOSS RFC and it is working fine. Even, I have restarted the SAProuter services through command prompt but nothing worked, getting same message. Please someone help me to fix this.

Regards,

We have 2 Routers and I had this issue (Host did not respond 1,2,3.. and goes on) for weeks and months with both the Routers, at last the problem was solved forever. Our organization had blocked traffic from other countries and when SAP tries to connect it would never let them in. So the network/firewall team has added SAP's IP in the exception and it was quick as well. So this problem is gone forever. Hope this helps to people like me who had issues.
