I've seen many related posts - but no solutions to this issue. Sad

We recently updated our 3CX Phone System and as part of the process updated the firmware on all our phones, T42G, T42S, T42U. Now they are all making it very hard to get to the web administration gui of the phones. (navigating to their IP address)

We get the dreaded, "This connection is not private" and if you show details, "The certificate is not valid." For many browsers/OS combos we can't get past this screen.

All the phones have factory installed certificates and I can't figure out how to fix/change this. I found an article on yealink phones and certificates in general - but it's not helpful.

Has anyone come across this and figured out a solution?

1,000 thanks for any help.

Tom
