MicrosoftMicrosoftHello YutangLin,
We have been experiencing issues with TLS 1.3 in Azure Region US East since Thursday, January 23rd, 2024.
Our environment was fully functional before this date; we had no changes or deployments that would have impacted our systems. In researching the issue, we found this blog and no other resources. We have two cases open with Microsoft, both pointing to this blog with a point of concern as we began to see our Azure Web Apps, Service Bus, and other Azure services begin communicating on TLSv1.3. As a point of interest, our environment running the same configuration in the EU is not experiencing any issues.
We, too, are experiencing this same error: "The SSL connection could not be established, see inner exception. Received an unexpected EOF or 0 bytes from the transport stream."
We also see the error "The SSL connection could not be established."
Azure support asked us to try to add a certificate path exclusion of "/" to our web app services - they suggested that this would enforce TLS 1.2, which we did. However, this did not resolve anything.
[ web app -> configuration -> general settings -> Certificate exclusion path | value: / ]
