Add-TeamChannelUser fails with BadGateway - used to work

Add-TeamChannelUser -GroupId XXXXXXXX-YYYY-zzzz-jjjj-TTTTTTTTTTTT -DisplayName "Private Channel Name" -User First.Last@keyman .com used to work. Find now that I'm getting BadGateway errors (below). I'm a global admin in our Office 365 tenancy. I'm an owner of this Team. Sometimes we have to add significant numbers of people to different private channels in a Team. Doing this via Powershell is much faster than via the GUI. An additional issue is that if ever all the other owners of a Private Channel leave the company, any other owner needs this command to get into the channel. This was working but no longer today.

    This seems like an issue at the backend, best open a support case.
