HTTPS Error for Cisco C3850 24P

Hello,

 

When I try to access one of our switches via https, we get the "This Page can't be displayed" or "This site can't provide a secure connection" This was working before a power outage occured and when it was restored, it seems to have broken.

 

http and https are enabled. HTTP and ssh are working fine:

 

ip http server
ip http access-class 10
ip http authentication local
ip http secure-server

 

I've tried to delete all keys using "crypto key zeroize rsa" and it did not seem to help. I've also tried to create a new key "crypto key generate rsa modul 1024" and only ssh and http works.

 

Any advice?

 

Thanks!
