SSO broken after updating to




Our PRTG updated this morning and since has broken SSO. Having retraced the setup we can confirm no settings have changed, has anyone else had any issue with this version?

The error when attempting to login via SSO - "Your login via SSO has failed. Please contact your administrator!" We can see the authentication in Azure and it looks okay.

And when testing Single Sign on authorization endpoint the error is - "generic exception during test: Failed to establish secure connection"
