See post #2I use https over 8443 for local administration and just upgraded my AC66U from 380.63_2 to 380.64_1.
After the successful upgrade and reboot (from ssh), a new https-cert was created (valid from just then and 10 years forward), so I had to export the cert chain and put it on in trust list in Chrome. That is all expected behaviour.
But after a few changes in the DDNS section I rebooted the router from the webui button. Afterwards the cert was not recognized anymore. It turned out, the https cert served from the router was an old one valid from August 1 2015. Since, to my knowledge, a new cert is generated upon every firmware upgrade, this seems like a bug.
Anyone experiencing the same?
