Our static website which was created on 2021, and was working all OK is suddenly down. Unable to reach via custom domain and the internal domain. Upon checking the SSL, found a new SSL certificate was issued this morning with wrong CN. Please look at this issue URGENTLY!

    Hi @II

    Thank you for posting your question on Q&A.

    Our engineering teams are actively investigating and addressing the underlying causes that are impacting Static Web App availability.

    In the meantime, some customers have reported temporary workarounds such as creating a new Static Web App instance and re-adding their custom domains, which triggered the provisioning of new SSL certificates and helped restore access.

    Please note that deleting and re-adding custom domains alone has not consistently resolved the issue.

    Please feel free to post back if you have further questions or if the issue continues after trying the suggested approaches.
