After a little hiatus from blogging, I am back at it and my first order of business was to create a few more items around Azure + vRA that were top of mind.

After logging into the lab after a couple idle months noticed it was nearly inoperable. After a reboot of everything including my ESXi host, everything looks like it was back up and running until I came across this error:

Azure Endpoint: Error in plug-in

vRO azure error in plugin

After further investigation, I found this error:

Exception: Unable to execute ‘fetchRelation’ for type : Connection :

com.microsoft.windowsazure.exception.ServiceException: ExpiredAuthenticationToken

 

I logged into the Azure Portal to check that my App Registration and APIKey were still valid, and they were, odd. (Azure Portal->Azure Active Directory->App Registrations->(Click on App)->Keys) I then created a new Key and updated the Key in vRA under Administration->vRO Configuration->Endpoints->Azure->Client Secret. This worked for about 8 hours and then I got the same error. Repeated above steps and same outcome. Interesting…

I never did find the root cause, but after this error came up again later the same day, I created another Key in the Azure Portal, rebooted the vRA and IaaS server, updated the “Client Secret” again and then rebooted the vRA server again. This seems to have worked as I’m going on day 3 and it is working as it should be. Again, I never found the root cause, but the only thing I can think is that it was a connection issue between the IaaS and vRA server or possibly since it had been sitting for months unused, there may have been some stale data in the database that wasn’t getting updated for some reason.
