It has been a while since I did a local access to my Duo ( https://192.168.1.100/admin/ ) I am getting certificate errors now in Chrome (ERR_SSL_VERSION_OR_CIPHER_MISMATCH); Firefox v63.0.1 (SSL_ERROR_NO_CYPHER_OVERLAP) The best I can do is to access the shares forlder insecurely.( http://192.168.1.100/shares/ ) Which is hardly enough to administer the NAS. I think that the latest versions of the browsers are all implementing secure connections without any way to bypass it. How do I fix this?

You shouldn't be allowing over-the-internet access to your NAS anyway, since it's been EOL for a long time, and isn't getting security updates.

They won't if you disable https on the Duo (which is an option under services). Though the trick now is to get it to connect once, so you can do that. You could try using IE perhaps in compatibility mode, or temporarily installing an older version of FireFox or Chrome. FWIW, I am not seeing this issue on my own Duo and NV+, and both have https enabled. FireFox and Chrome say they are up to date, though Chrome is version 70.0.3538.102, not version 71.

I was able to connect to Duo v1 using Safari on an iPad. The browser there allowed me to bypass the warnings and connect anyway to the Duo. How/where do I disable encrypted TLS/https access to the device? I expect that will be good enough security as this is inside my LAN and with a local non-routable IP address 192.168.1.100 PS: Will it help to re-start the device? Aloke
