I am upgrading a client from EQ 5.5 to EQ 5.7 and need some help. They have a mixed fleet of SOP (cheetah V2.0) and GWNX panel devices.

The scan-to-me works selectively, looping endlessly on Please wait.

Challenges
•Scan-to-me loops endlessly on some devices
•Legacy devices will not connect to the new server running 5.7

Troubleshooting performed
•Updated device firmware - package and java
•Set device as MPC306/C406 using DRS. This got the scan-to-me working on MPC3004ex but not MPC6004ex

Additional Information
•All latest EQ hotfixes have been installed
