Error code: SSL_ERROR_NO_CYPHER_OVERLAP

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?

"This site can't provide a secure connection"

Is there a bypass button hidden some where?

I am not familliar with mac software

I have same problem as you

I bypass it with opera 12, witch have bypass option, witch other browsers doesnt

If that doesnt work, you can try mozilla esr release

https://ftp.mozilla.org/pub/firefox/releases/

in this link youn can find all mozilla releases

When I upgraded a zonedirect 1100 from version 4.x to 5.x I had that problem.
I found some technical notes that I had to restart the credentials in CLI programming mode and still continue with the problem.
I downloaded Opera and it did not work like the comments they make.
With mozilla I looked for some tutorials on TLS protocol and I did not succeed.
As I understand that version 9.5.1.0.50 uses different credentials. Meanwhile I want to try to make a downgrate to version 9.4.2.0.29.
Does anyone have a new opinion?
