We have recently upgraded the software on our two WLC 4404 from software release 4.0.xxx to 4.2.xxx to 18.104.22.168 and lastly to version 22.214.171.124.
We could access the WLC's GUI's using https when it was on version 4.0.xxx. When we did the upgrades from version 4.2.xxx to 126.96.36.199 we couldn't access the Admin page through https anymore but only through normal http. We enabled https through the GUI and through the CLI and we did do the re-generation certificate , without any success. We then upgraded to version 188.8.131.52 and we still have the same result , cannot access Admin GUI through https.
Any suggestions ?
