Pulseway/Windows Server 2008 Enterprise SSL/TLS Relationship Error


Recommended Posts

Hi There

We updated our Thawte certificate and applied the update to our dedicated pulseway server. We have a 2008 server that goes offline when applying the new cert, when we switch back to the old cert the server comes back online. We have an environment with over 70 Servers and this Windows 2008 enterprise server is the only one that gives us the following error when validating its credentials.



Please advise what steps to follow?

We have checked time and date settings, ensured machine is up to date.

All the best,

In that case, is it possible that you have enabled only TLS 1.2 encryption protocol on this system? If yes, then you will need to enable TLS 1.2 for .NET framework, by running built-in script 'Enable TLS 1.2 in .NET Framework 4.0' on this system.

Hi Chris

Thank you for the information. It would seem the older Cert we were using was compatible with .Net 4 but the new certs being issued support .Net 4.5 and above TLS 1.1/1.2 and above. As this is production machine ill have to schedule a .net upgrade which should resolve the issue. Will revert back with the outcome to help others experiencing this issue.
