Hi @zhoxing-ms , can you suggest some solution for this

[reisman234]

Hi @Sai-kesa, I faced also this problem in my script. As a quick (and maybe stupid) workaround, I added a retry loop around the az vm create command. My script look now like a mess but in 1 of 5 of that retries, the creation worked.

I'm using az vmss create, and encountered this error.

From the debug log,

No registered resource provider found for location 'eastus' and API version '2025-01-01' for type 'virtualNetworks'

This intermittent error is similar to what we're encountering across our organization as reported by different people from another projects, and It is getting more and more frequent. So, please help to fix this.
