OneDrive connection issue – login dialog closes immediately

Hello everyone,

I wanted to ask if anyone else in the community is experiencing a similar issue.

On my ZIMA installation I was initially able to successfully connect my Microsoft OneDrive account, and several backup jobs ran without any problems.

However, recently the connection stopped working. When I try to reconnect to OneDrive, the login dialog briefly opens but then immediately closes again before I can complete the authentication process.

Because of this, I’m currently unable to start any new backup jobs.

Has anyone encountered the same issue or found a possible solution?

Thanks in advance!
