I was not able to get firefox to work. I got the same messages that you did, and could not find any workaround. IE and Chrome Both gave me warning messages, but then provided me with the option to continue. Once they had the certificate added, I could then connect without issue.   I tried using SSL3 and TLS1 protocols on the switch, and both produced the same results for me. I played around with some of IE advanced settings, disabling some of the checks for certificate revocation, but none of them seemed to change the behavior. I also tried enabling Chrome's option to allow invalid certificates, but it had no effect.   I am not certain what else we can try here. I suggest using IE or Chrome, and see if you can get that option to continue. Perhaps also try a different client to make the connection from. [IMAGE] 
Hi Dell Community, When browsing to my N1548P switches web management via HTTPS, I get this error in Firefox.I get similar errors in Edge and Internet Explorer. I have followed the steps described in in HOW10832 "How to set up management access for the N1500 series switch" I have generated RSA and DSA keys and have "ip http secure-server" set in the configuration. I have NOT disabled HTTP (I tried that, but I put it back because HTTPS doesn't work)I am able to browse by HTTP with no issue, and I can ssh to the switches with no issue. The switches are on firmware 6.3.3.10 which I understand is current as of November 2017.My X1000 series products do not have this issue and I can browse to them with HTTPS.Any suggestions? Thanks! :)[IMAGE]
