Unknown Error - Validation Failed - Custom Domain for Static Web App

Question

I tried buying a domain through azure, it gave my resource group a DNS zone so I tried adding it to my Static Web app. It took a few days of validating then failed. The message displayed is an unknown error. I have tried for a few days to see if it would update but has not. The generate code button gives the same error.

What should I do? How do I check if I actually own the domain?

Hi @Matt Esposito ,
welcome to the Microsoft Q&A Platform!

• Go to Azure Portal > App Service Domains (or Azure Portal > Domain Services if purchased through Azure).
• Check if the domain is listed under your account and marked as active. If it’s there, this confirms you own the domain.
• Go to the DNS Zone created in your resource group.
• Verify that the TXT record for validation exists and is correctly set up:
• Host should usually be @ (root domain).
• Value should match the code required for your Static Web App validation.
• If the TXT record is missing, manually add it based on the required values from your Static Web App settings.
• Use a tool like MXToolbox TXT Lookup to see if the TXT record has propagated. Enter your domain, and if the TXT record is visible, Azure should be able to validate it soon.
• After confirming the TXT record is visible globally, try clicking Generate Code and Validate again in Azure.
