o365 Add-On error can't complete tenant edits

[mikefg]

o365 addon has been running fine.

Token expired on the Azure side, so I generated a new one.

Updating the Splunk addon gives me the error "Only letters, numbers and underscores are supported." and highlights the Tenant Subdomain or Tenant Data Center fields (see attachment).

I can't complete the update without values in these fields.

Not sure what to do here.

Figured it out, just didn't enter anything into the optional Cloud App Security Token, Tenant Subdomain, or Tenant Data Center fields and that got it working again.
