Hello Rahul,
As per screenshots shared your Deployed Dev Studio service version is 8.0.12 while your Dev Studio eclipse plugin version is 8.1.15
Due to this version mismatch, you are getting the error while accessing SAP IDM Developer Studio.
Please Upgrade your SAP IDM Dev Studio Service to 8.1 (Recommended) otherwise install the Dev Studio eclipse plugin version 8.0
Regards,
C Kumar
