Hi,
We are facing a weird issue with MWS.
MWS Process is available and logs shows MWS is initialized successfully but MWS login page is not displaying and we are getting below error, when trying to access the MWS URL.
Can anybody throw some light on this error please?
Thanks in advance.
Note: We haven’t installed any new fixes, no changes were done to MWS but suddenly we are facing this problem.
