Sync to cloud (linking) error

[julianbr]

Hi! 

I need some help linking the installation to the cloud. I'm stuck on the current error: Initial push failed. Automatically retrying in 15 minutes. You can also retry the initial push manually. It always happens after "backing up database".

sync_errorlog:

2022-08-11 08:44:33,485 [86] INFO  LOGLANSWEEPERENTERPRISE ERROR Error creating backup  The backup cannot be performed because 'INIT' was requested after the media was formatted with an incompatible structure. To append to this media set, either omit 'INIT' or specify 'FORMAT'. Alternatively, you can create a new media set by using WITH FORMAT in your BACKUP statement. If you use WITH FORMAT on an existing media set, all its backup sets will be overwritten.

 All scan servers are running version: 10.2.3.0

I have tried to unlink/linking multiple times and all prerequisite checks are green.
