Changing Server Name POST error

[JonasPonas]

Hello everyone,

Server:  Synergy 480 Gen9 iLO 4

Powershell module: https://www.powershellgallery.com/packages/HPEiLOCmdlets/3.0.0.0

When running this command:

Set-HPEiLOAccessSetting -Connection $iLOConnection -ServerName "WIN-GSGSGS"

I get this error: 

POST in progress, try command later.

I can't even change it manually. When editing manually i am getting this error:

Server may be at POST. Server Name can not be set during POST.

How you could I change the server name? Any help or pointers are much appreciated.
