Hi. Thanks in advance.
Windows 2012 R2, WebSvr1 and WebSvr2, load balanced.
Code is identical between both web servers and IIS is the same too. I did an export of site and server and verified.
Bindings and certificates are identical between both machines:
IP address: "All unassigned"
If I stop IIS on Web1, I can access Web2 from both the server itself and from my local machine.
If I stop IIS on Web2, I can hit the website from the server only, but not from any other machine. I get:
This page can’t be displayed
Make sure the web address LSC2DDR.Domi.site is correct.
Look for the page with your search engine.
Refresh the page in a few minutes.
If I stop IIS on Web1, I can immediately get into my website. Also, I clear the cache and close IE before each login attempt. Browser versions don't seem to matter here.
The worst part is that there are no errors in the Event Viewer on my local machine or the web server. The IIS logs show 302 0 0 0. Generally speaking I know this has to do with "object moved", but nothing has changed regarding locations of code or anything.
We recently updated to TLS 1.2 though. This may or may not have anything to do with things. Because they're load balanced, this error could have been around before the change to TLS 1.2.
Does anyone know where I should troubleshoot next? I've tried to compare everything but so far, everything is identical between the working and non-working servers. I really don't know what to do next.
Thanks for your help.

Did you created the Web farm on WebSRV2?

I don't know how to answer that. The farms were set up long before I came on to this project and I have no access to anything IT. I just manage the servers and IIS (etc) where code is deployed. I can tell you that it's been working for years with no changes
to the farm that I'm aware of. Lately, the only thing that's changed was the TLS 1.2 upgrade but as mentioned, Web1 may have been malfunctioning before TLS because it's load balanced and I may not have caught it.
If Web1 has been malfunctioning, it would have only been for a about two weeks tops, as we did some testing pinning to individual servers. So the problem is very new.
Do you have any ideas for me to troubleshoot? I'm not understanding why we're getting 302 errors in the IIS logs. I've checked the configuration on both machines in IIS as well as certificates and I can find no differences. With so little info in the
error logs it's hard to know where to look.

For some reason, the only person who can't hit the "problem" website is me. Other's can, I can't. In spite of clearing browser cache each time I launch a new IE (via Win Explorer because when I clear cache from the browser, some files are always remaining),
I can't access the page. I even tried creating a new session in IE but, nooooooo. I've even tried different browsers and I cannot access that page.
Thanks Deepak for the quick response. I'm going to chalk this up to gremlins and move on to other things.

Try to check the redirection rules. It is possible that something got changed cause this issue.
It possible that on your machine there is any rule that redirect the request.

Turns out my profile was messed up somehow. It was rebuilt today and I magically and (not) surprisingly no longer have any issues. Imagine that. :) Thank you so much for your assistance and very fast responses. Your attention is much appreciated.
