Reporting Services Website Accessible By IP Only

Points of My Scenario
1. I am admin of a Reporting Services (2008 R2) website that has been working until this morning.
2. Issue: users are now unable to authenticate/access it by its FQDN (fully qualified domain name) - it keeps prompting for credentials
3. When users type IP address instead of the FQDN, they can access the website

QUESTION: How can I resolve this issue so that users can once again access it via the FQDN?

Hi Walt,

Has the certificate changed at all, e.g. expired, etc?
Is the web server's DNS pointing to the DCs?
Where do the users access the website from internally, externally, or both? And can you duplicate the issue in both if they apply?

Let me know how it goes!

1. The site does not require a certificate
2. The web server's DNS is pointing to the DC's
3. Website access is internal only

Many thanks for your attention thus far.

Can you access the website by FQDN from the report server directly?
Were windows updates applied?
Do you get any errors?

You might have an issue with loopback, you might try testing the registry changes here
