We have intranet websites in an enterprise environment. About a month ago, we started receiving emails from users who were unable to reach pages on a specific server. There are hundreds of users for this particular site and about 20 have reported that they get "connection refused" messages in their browser when clicking a link to this site.
After investigation I found that their browser was forcing an http link to https. The site does not use https. These corporate PC's have 3 browsers installed. IE, Edge, and Chrome. All 3 browsers force https to this particular server. The link looks something like this:
So I had them try this instead:
And it worked. It did not force https and the users were able to navigate to the page.
Since it's a relatively few people experiencing this issue, I'm thinking it's PC specific and I tried browser basics like clearing cache, cookies, etc. But that didn't help.
If something was misconfigured in the server it should affect everyone but it isn't.
I have searched for this issue and the only results I get are how to configure a server to redirect to https.
The easy fix would be to tell all users to start using the servername link instead of the alias. But that's not ideal and the list of users affected by this is growing by about 2-5 people every week.
What could possibly be causing this? Any suggestions?
