Description

Azure Static Web Apps deployment is consistently failing with infrastructure-side errors across multiple retries. The build completes successfully but the deployment pipeline is unreachable.

Environment

  • Region: East US (or confirm yours)
  • Workflow action: Azure/static-web-apps-deploy@v1
  • Deployment ID: 0385cc24-aeff-4945-9382-cc53c1e53c49
  • Date: 2026-04-23

What happens

Three consecutive failures with different error patterns, all Azure-side:

Attempt 1 — fails during polling after upload (9 min):
Finished Upload. Polling on deployment.
Status: InProgress. Time: 537s
Deployment Failure Reason: Invalid API key.

Attempt 2 — fails after upload:
We are currently experiencing problems communicating with our content server.

Attempt 3 — fails before build even starts:
Looking for event info
We are currently experiencing problems communicating with our content server.

Azure Portal — also timing out when resetting deployment token:
Resetting token failed with the error: {"code":"ServerTimeout","message":"The request timed out.",
"tracking id":"e637de4a-316d-4f9b-9f30-6e029f767e48"}

What was verified (not the cause)

  • ✅ Build completes successfully (2003 modules, Vite)
  • ✅ API token was reset in Azure Portal and updated in GitHub Secrets
  • ✅ Workflow updated to actions/checkout@v4, OIDC removed
  • ✅ TypeScript compiles without errors
  • ❌ All failures are on Azure's deployment infrastructure side

Expected behavior

Deployment should complete after upload finishes.
