Catalyst 9800: SSH Works, Web Interface Fails with Invalid Credentials

[prcant]

I recently configured a Cisco Catalyst 9800. After setting up the device via the console, I enabled the web server and configured the management interface along with user credentials. SSH access is working perfectly, but when trying to log into the web interface, I receive an "Invalid Credentials" error.

Steps:

1. Configured the management interface with an IP address.
2. Enabled HTTP/HTTPS server.
3. Created a user with privilege 15.
4. Enabled SSH access, which works without issues.

What could be causing the web interface to reject the credentials while SSH works fine? Are there additional configurations required specifically for the web interface? Any guidance would be greatly appreciated!

Validate the WLC config with WLC Config Analyzer https://cway.cisco.com/tools/WirelessAnalyzer/ and go through the critical Advisories and fix them.
