WHy can't I log into my college website anymore?

Because the failure occurs in multiple browsers and devices, test the official KU sign-in from a different network; if it still fails, contact the KU IT Help Desk rather than changing the Windows firewall.

1. Test without network filtering

1. Open KU’s official Enroll & Pay / CS Student Information page: ^1^
2. Temporarily disconnect any VPN and disable custom DNS, parental controls, or web-filtering/security software. KU notes that these can interfere with access to its services.^2^
3. Connect one device to a genuinely different network—for example, disconnect it from Wi-Fi and use cellular data—then try again.
   • Works on cellular: the original router, DNS service, VPN, or security filter is blocking KU. Re-enable each item individually to identify it.
   • Still fails on cellular: move to the KU support step below.

Do not add KU as a Windows “trusted site” or broadly disable the Windows firewall. KU’s Firewall Management page describes an administrator-managed service, not a normal student sign-in remedy.^3^

2. Check KU’s central sign-in

Try KU’s central Single Sign On page directly.^4^

• If central sign-in also rejects the account, the KU Online ID may be locked, expired, or otherwise require KU to check it.
• If central sign-in succeeds but Enroll & Pay fails, report that distinction to KU because it helps isolate the affected service.

3. Contact KU IT if it fails on another network

Use KU’s Student Technology Help options.^5^ Include:

• The exact message shown on screen.
• The date and approximate time of the attempt.
• Whether both central KU Single Sign On and Enroll & Pay failed.
• That it failed in multiple browsers, on multiple devices, and—if confirmed—on cellular data.
• A screenshot with your KU ID, email address, payment details, and other personal information hidden.

Repairing or resetting Edge is not the next step here: Microsoft states that when a page also fails in another browser, the network or website may be responsible and the website owner should be contacted if network troubleshooting does not resolve it.^6^
