I used to be able to access a military facility web site, but now I cannot. I get the 403-Forbidden: Access is denied because I do not have the appropriate credentials. I have not changed any thing on my computer to cause this issue. This is the first time that this issue has occurred. I have accessed the web site many times in the past without any issue.

I am able to access the web site that is at issue with my IPad without any problem.
