An exception has occurred at updating provisioning settings

Every time I am trying to modify anything in the Provisioning portian, I am getting the above.

Whats interesting is that some setting do apply but most of them does not

Pleas give more information and screenshots.
What phones? When does this exactly happen?

It’s not any specific phone, its in the provisioning in general

Try reinstalling the add-on.

I already tried that,

but the issue seems to be that the Provisioning server HTTP/HTTPS ports arent the default.

Once I changed it back, all was good
