When using CNUT 5.0.3 to upgrade our subscriber units to the latest 21.1 firmware for the PMP450, we are getting the error - Incorrect upgrade image attempted for specified device or Failed to set max file size (status:256).
We have upgraded the access points (PMP450i) with no issues and are running 21.1.
Some of the subscribers did update to 21.1 - but most failed with this error, and they range from 450b mid gain, older pmp450, and 450b retro units. (HW platform 11 and 15)
Curious if anyone else is having these issues or have seen it before?
