We have an issue on servers where TLS 1.0 and 1.1 have been disabled. If you access Admin using https and try to run a data integration job, an error is returned. The error is: 'Web exception occured: The underlying connection was closed: An unexpected error occurred on a receive.' This only happens if both TLS 1.0 and 1.1 are disabled. If TLS 1.1 is enabled, running the job from Data Integration works fine. Is this a known issue? Is there a workaround without enabling less secure protocols?

Thanks,

Terri

Is this the same thing as with the connectors? Should we explicitly enable TLS 1.2 through code?

Yes, it looks like you need to enable TLS 1.2

You can either...

A) Enable support for TLS 1.2 through code at startup (before any web requests).

ServicePointManager.SecurityProtocol = ServicePointManager.SecurityProtocol | SecurityProtocolType.Tls12;

B) Upgrade to Dynamicweb 9.4.0 or later.

We have enabled support for TLS 1.2 by default.

Best regards,
Morten
