Hi,

 

I've got custom connectors and have started getting this error code when refreshing the connections, this is happening across multiple accounts i can't find any info on it googling or on the MS help guides, anyone know what could be causing this?

    Same problem here. Anyone from Microsoft here?

    I could fix it. There was obviously a change in Azure AD and I had to re-enter the reply URL (which you find in your custom connector's security tab at the bottom). After doing so, it all worked again.

    Thanks for the update, i'm having an issue my custom connector is no longer displaying a reply URL and i can't enter one, even if i create a new custom connector still don't get a reply URL, any ideas?

    Sorry, no idea with this one. And I think it is a different issue and you perhaps should start a new thread for it.
