Azure Arc Service Principle link Broken?

Question

Azure Arc Service Principle link Broken?

Baldwin, Joshua 0

When i try to setup a service principle under Azure Arc, as soon as i click the link it seems like it kills the page. No other links on the left menu seem to work. Is there a current issue im not seeing? Refresh does not work, and i have to go to my Arc subscription, then navigate back to Arc and im able to interact with the page again.

Thankyou **Adithya,

**When i looked at the service health i did not see any issues reported either. This morning it seems like the service principal is working.... so far. If it goes down again, i will try the CLI route. Appreciate it much.

Hi Baldwin,

This behavior looks like an Azure portal blade/UI failure rather than a service-principal permissions issue. I found another report describing this exact Azure Arc behavior from August 4, 2026, but there is currently no published response confirming a widespread outage or known issue. [learn.microsoft.com]

Recommended checks

Check Azure Service Health for active or emerging issues affecting Azure Arc, Azure Resource Manager, or the Azure portal in the affected tenant and region.
Reproduce the issue in an InPrivate/Incognito window.
Test with another supported browser and temporarily disable browser extensions.
Clear the browser cache and site data for portal.azure.com, then sign in again.
Confirm whether the problem affects:
- All users or only one user
  - All subscriptions or one subscription
    - Multiple tenants
      - Multiple browsers and networks

Workaround

You can create the Azure Arc onboarding service principal through Azure CLI instead of the affected portal blade. Microsoft documents Azure CLI, Azure PowerShell, and Azure portal as supported creation methods. The identity should receive the Azure Connected Machine Onboarding role at the required subscription or resource-group scope. [learn.microsoft.com]

az login

az account set --subscription "<subscription-id>"

az ad sp create-for-rbac </span>

--name "<service-principal-name>" </span>

--role "Azure Connected Machine Onboarding" </span>

--scopes "/subscriptions/<subscription-id>/resourceGroups/<resource-group-name>"

Store the returned appId, password, and tenant securely because the secret is displayed only when created.
