What have I done so far:
tried to do an update via the OC200 = Failed

tried an update via the device management page = Failed

disabled pihole etcdisabled Switch ACL's

This is the first time I am upgrading an es205g via omada, never had this issue with upgrades of other devices.

The only test which i have not done is to remove the device from omada.

The OC200 v1 is currently running on 5.15.8.12

furthermore I have the following devices running via omada:
2x EAP225-Outdoor(EU)v1.0 Version: 5.1.7
3x EAP245(EU) v3.0 Version: 5.2.0
1x ER707-M2 v1.0 Version: 1.2.3
