Deactivation of Transport Layer Security (TLS) 1.0 and 1.1

Microsoft announced the deactivation of Transport Layer Security 1.0 and 1.1
Announcement from Microsoft on September 30th, 2020:
Transport Layer Security (TLS) 1.0 and 1.1 are security protocols for establishing encryption channels over computer networks. Microsoft has supported these protocols since Windows XP/Server 2003. However, due to evolving regulatory requirements as well as new security vulnerabilities in TLS 1.0, Microsoft recommends that customers remove TLS 1.0/1.1 dependencies in their environments and disable TLS 1.0 and 1.1 at the operating system level where possible.

PTV xServer internet with API version 1 will no longer be able to support TLS 1.1 or lower by the date September 30th, 2021 due to security updates in Azure.
PTV will start to deactivate the protocols with the planned map updates starting in October 2021. The updates will be announced via our PTV Developer Blog. You can subscribe our blog to stay posted.

  • Your action is required if you are still using TLS 1.0 or 1.1 version, as the requests will not get through to our service after we update the map clusters.
  • If you still use .NET Framework version 4.5 and lower or Java 7 runtime and lower your action is required.
  • Update your framework to a newer version to guarantee access to our service after the update on our map clusters.

.NET Framework
We recommend updating to NET 4.6 and above. You don’t need to do any additional work to support TLS 1.2, it’s supported by default. More detailed information regarding different NET. versions can be found here:

PTV Java Clients
We recommend updating to a Java 8 runtime environment for the PTV xServer clients because Java 8 runtime supports TLS 1.2 by default.
