Hi team,

Failed to process the request: Request refers to an unknown session

While clicking on the same , 2-3 times , although the error goes away , but appears again after sometime.

This is faced daily and comes on and off. Screenshot attached hereby.

Please let us know the resolution for the same.

IMO, It happens the third case c.

the target system uses session and maintain your user credentials (login details). If the session timeout, the credentials are removed from the session and so when you click more than one time, it creates one on the target side and maintains again.  This session stays alive for some particular duration. If there is no trigger from interface the session fails and create one after your first call again. So you see this problem intermittently. Whenever you hit after a big pause, you see for the first call this problem and the target loads again your credentials and that takes delay and your subsequent call get connection.

Yes if the session is the real issue then it happens mainly for the first time.  I would recommend this way.

If the target system requires session to be maintained to process the interface, then during rmapping you can simply sign on process first  and after successful logon then send the request. This two steps could help to avoid this problem.
