Failed to create service principal while trying to register azure stack hub with azure

Question

I have a newly installed Azure stack hub (full-one, not ASDK) and the external network is connected to the internet via NAT. It is version 2102 and I downloaded the 2102 tools from GitHub to do the registration.

But trying to run the registration, I get the following:

Searching showed a similar error around two years ago which was resolved using a longer timeout. I checked my scripts and I had the recommended change and it does not take 30 mins for each retry to fail (more like 2 minutes) so it doesn't seem like it is really hitting that timeout. I don't think there is any firewall in the way and there is no log indicating a connection failure so I'm not sure what could be happening.

Answer 1

To start, make sure you are using the AZ modules, not the AzureRM Modules. You can select the module based upon the tab at the top.

next, if it still is unable to register, try using the register in the disconnected environments instructions. Sometimes connectivity issues with the machine can cause this issue. You register with a separate computer and bring the registration to your ASDK machine.
