Microsoft released on May 10th a security update to patch a vulnerability within the Microsoft .NET framework. This update, while helping protect your system causes two symptoms within Venafi that we have discovered:

Current Workaround:

If you have already installed the patch on your server and experience these symptoms, removing the patch will let Venafi return to normal operation.

You can implement Microsoft's workaround instead of installing the patch. You can find them in the 'Workaround' section Microsoft provides here:
