Get-ConfluenceSpace throwing HTTP 500 / not working

[Constey]

Since a couple of months the Get-ConfluenceSpace is not working anymore for me. The only thing changed is the Confluence Version itself i guess.

Has anyone the same problems?

Import-Module ConfluencePS
Set-ConfluenceInfo -BaseURI 'https://confluence.fqdn' -PromptCredentials
$spaces = Get-ConfluenceSpace
