Old ZD needs an update.

Firefox shows me this:
 Cannot communicate securely with peer: no common encryption algorithm(s). Error code: SSL_ERROR_NO_CYPHER_OVERLAP

I used to be able to bypass that using Firefox, so I could install the latest software. This ZD has not been even looked at in years. But with the certificate expired... 

Any suggestions?

upgrade at least to version 9.7.2.
Probably you are using Windows 10, we experienced the same Problem.
use another Computer to access your ZD to upgrade.
after the upgrade you will be able to connect.

I did the update with Firefox on all the ZDs I manage months ago. This was one of those "break fix" installs.

I installed Opera on my Windows 10 computer and I get no option to Bypass. Will try it on a MAC now.

Did you install opera 12 or opera 41, because opera 41 has no bypass option (for me)

"This site can't provide a secure connection"

Is there a bypass button hidden some where?
