Netscreen ERR_SSL_VERSION_OR_CIPHER_MISMATCH

I can no longer access my Netscreen ns25 firewall.  Firefox and Chrome give error ERR_SSL_VERSION_OR_CIPHER_MISMATCH. Nothing has changed on this firewall for years and now I can not access the GUI. Does anyone have a work around to restore the firewall or is it time to replace it?

Your browser no longer accepts older versions of ssl certs. I use an older version of Firefox to get around this issue. You can also disable ssl for the webui via the command line.

I am a GUI guy. Can you help with the command to disable the web gui ssl for trust interface?

Hi Avsc,

The command is:

unset admin http redirect

( i acutally found it on an old post I made on EE from 2010 :)

BUT!!

before you do that. please try installing IE-tab for chrome plugin from the plugins store: https://chrome.google.com/webstore/detail/ie-tab/hehijbfgiekmjfkfjpbkbammjbdenadd?hl=en

This is a better option than disabling what little security you have.
