I manage an application server in a different department from IT and since they implemented a new firewall as part of emergency maintenance, users are having issues accessing the web app(Blackboard).
When you configure Blackboard and install it, it automatically creates the website in IIS, and creates two headers binding https, port 443, on IP address *, and another with http, port 80, IP address field is blank.
Before this new firewall, browsers would resolve either port 80 or port 443 fine. Requests to the port 80 for the website would return the secure(HTTPS) page. The issue now is that students and faculty are having issues getting to the page when they're off campus because our network/the firewall(I believe anyway)is not redirecting the port 80 request to the 443 port.
Basically, when users try to access the site, and just type in the URL without any
https:// header in the address bar, their browser assumes a port 80 request and tries to connect to
http://www.appserver.com thus our network isn't delivering it back. If a student puts in
https:// manually in front of the URL, the app server loads perfectly fine.
So is there a firewall, networking, or server OS issue? I haven't touched anything before or after their maintenance and that's when the issues started. If it is, what needs to be changed and what should I tell the IT guys to look into to see if they can identify the issue?
