Hi @Egor Skepko , thanks for the post!

I see a few cases with this error, with a few fixes:

• "cvping management.azure.com -port 443" didn't work due to name resolution issue.
• App login credentials were inccorect
• Application Subscription ID had expired
• Resolved in 11.26.4

The last one is pretty specific, though I don’t want to leave anything out!

@Mike Struening Thank you, we are running 11.28, that mean that issue with subscription ID Expired  fixed? Or you mean that ID is not vailed anymore ? 

What Maintenance Release?  The fix (for that one case) was in 11.26.4, though I don’t want to assume it was in 11.28.0 (though it VERY likely was).

I would look at the other 3 fixes (note that each one is not connected, they are all separate case fixes).

@Mike Struening  Atm we are on release 34, release 38 is also out for instal.

It’s likely not an update issue then.

I would try each of these:

• "cvping management.azure.com -port 443" didn't work due to name resolution issue - Check name resolution for managementment.azure.com at port 443
• App login credentials were incorrect - confirm the app credentials are right
• Application Subscription ID had expired - confirm the sub ID is still valid

If none of these work, I would suggest creating a support case.

@Mike Struening I think the issue is resolved now, The ID is not expired but we are used the wrong authentication ID, the cvping didnt worked because the mistace in the proxy. So you can close the case. 

appreciate the follow up!
