OneDrive personal Authentication failed on freenas 11.3-U5

[benji791]

Hello all,

I have a freenas server that was born a "few" years ago with version 9.10. I upgraded it other the years until this week where I decided to jump from version 11.1-U7 to 11.2-U8 and finally 11.3-U5.
On this server, in version 11.3-U5, I can't set up OneDrive personal credentials.
I am able to login to provider and the appropriate fields are correctly documented. I am able to choose drive id and get this result

Then when I want to verify credentials, I get this error :

I've tried exactly the same procedure on another instance where I started installing yesterday from green field 11.2-U8 then upgraded to 11.3-U5. And it works without any issue (of course I've deleted in between the authorizations for truenas in my microsoft account).

I've looked at middlewared.log on the first server with the issue and I don't see any more details. Where could I look at to troubleshoot the issue? Is there any log file that could be of any interest.

Please note that Google drive works on this machine

I'd like to avoid reinstalling a new machine and restoring a backup to it.

Thanks in advance for you advices.
