RFC_ERROR_COMMUNICATION - Connection timed out - BOBJ 4.1 - SAP BW connectivity

I am running into this issue when trying to connect from BOBJ 4.1 server to SAP BW server.

And this happens randomly, especially if the system is idle overnight and next day morning I see this error when trying to connect.

After 2-3 failed attempts, then it connects fine. It will work fine then.

After 3-4 hrs when I try this again. it again fails. Never had any issues for the past 2 years and now we suddenly see this happening.

I found the below error in the dev_jco_rfc file.

The same error shows up in CMC when I try to import roles from BW in the Authentication - SAP area of CMC.

Can you  please advise. Thank you.

I just marked the sensitive information below in the error message with "*"

    Hi Summa,

    Rfc Statsus clearly says Destination host is not reachable,Try to ping your partner host if it is fine ,There might be some network issue ,Try to make a entry in host file .
