TLS certificate expired on *.swedencentral.inference.ai.azure.com

Question

I’m encountering an issue with a TLS certificate used by one of the managed endpoints under the domain *.swedencentral.inference.ai.azure.com.

Specifically, the certificate expired on May 17, 2025, and it’s causing TLS verification failures when trying to connect to serverless inference endpoints. This appears to be Azure-managed infrastructure (Microsoft Azure RSA TLS Issuing CA 08), so I believe the certificate renewal may have failed or been delayed.

Other related subdomains like *.swedencentral.models.ai.azure.com are working fine with valid certificates, so this seems isolated to the inference.ai.azure.com path.

What's going on?

@MORAVEC Jan welcome to the Microsoft Q&A community.

It sounds like you're running into a certificate expiration issue on Azure's managed infrastructure. If the TLS certificate for *.swedencentral.inference.ai.azure.com expired on May 17, 2025, and hasn't been renewed, it could be due to a delay or failure in Azure's automated renewal process.

Since other related subdomains like *.swedencentral.models.ai.azure.com are functioning correctly, this suggests that the issue is isolated to the inference path. You might want to check Azure's status page or relevant support channels to see if there's an ongoing incident or planned maintenance affecting certificate renewals.

If this is causing disruptions, you can try:

• Manually verifying the certificate using tools like OpenSSL to confirm its expiration.
• Checking Azure logs for any renewal failures.
• Reaching out to Azure Support to escalate the issue if it's not being addressed automatically.

I hope these helps. Let me know if you have any further questions or need additional assistance.
