HTTPS not working on CBS350.

[Michael_Hansen]

Hi All

I have  a network with 26 CBS350-24 switches, all with the same "error"?

I have disable the HTTP server, and only have the HTTPS and SSH active. But when i try to connect to the webGUI using https, i get the "not secure" warning. When i investigate the browser, it says the cert is not valid. If i investigate the CLI, logging show i conenct with HTTPS with cipher"something". How do i get a valid https connection. I have tryed to remake the two certs, make mgmt rule etc. The switches has internetconnection so they should be able to auth the certs.

Best Regards / Michael

@Michael_Hansen hi by default switch using self signed certificate to admin login via https. so its normal to have a certificate warning. 

if you want to add a certificate signed by different CA use below method. this link is for the SG series. but process should be same to your model too. the setting placement on GUI may be different.
