When users visit a website hosted on a virtual server at a client site, they are getting a Error and have to refresh the page.
If I select the URL in the toolbar, and hit enter, the page refreshes and it comes up. but then I click on a menu option and it will then time out with the same error unless I hit the uRL and press enter to refresh the page. I have to do this every time I move from one link to another.
The server the site is on is Server 2016.
IIS is where the site is hosted.
I don't see any security updates with Microsoft that could be causing this block. The support entity told me to uninstall a specific security patch that isn't installed. So not sure where to go.
