authentication to o365 stopped working

[mcbradford]

For some reason, authenticating using the app is now not working. If I use a rest (though inputs) I get data back, but it is not parsed because it is not part of the app. We use Okta, but not 2FA for this account. It looks like the authentication issue is with Okta, because with the Okta logs I see the user agent as python. Has anyone else had this issue? Any way to get this working?

I started getting "ConnectionError: ('Connection aborted.', error(104, 'Connection reset by peer'))" in the logs:

index=_internal sourcetype="ta_ms_o365_reporting_ms_o365_message_trace-2"

Credentials are OK and I can download the message trace from the browser using those credentials.
