I'm getting a 401 error when I try to authenticate the integration

[TomCasavant]

This may just be an issue w/ a security policy setup on my work account, but I'm getting this error

Hi sorry I was on holiday with no access to email.
Can I have a bit more information?
Version of HA? using reverse proxy? Does home assistant run with an SSL certificate?

@TomCasavant - I was running into this too. I was trying out a different integration, and in the logs for that one, it stated:

"Unable to fetch auth token. Error: (invalid_client) AADSTS7000215: Invalid client secret provided. Ensure the secret being sent in the request is the client secret value, not the client secret ID"

So I went and made sure I was using the correct secret value and that integration worked. So I then came back to this one, and made sure to use the correct value (I wasn't previously), and now it's connecting just fine.

401 is generic when you get the Client ID/ Secret wrong (and probably other stuff..)

For me, when creating the secret within Certificates & Secrets >
You need to copy the key, not the the Secret ID

this is exactly was my issue, taking secret ID instead of KEY , now it is working
