Hi,

We just purchased a NSA 2600.  Once it is setup, I can not see the login page. Here is the error from different browser:

Google Chrome:
This site can’t provide a secure connection

192.168.78.4 uses an unsupported protocol.
ERR_SSL_VERSION_OR_CIPHER_MISMATCH
HIDE DETAILS
Unsupported protocol
The client and server don't support a common SSL protocol version or cipher suite.


IE:
please be patient as you are being redirected to a secure login page  (That means the box is working)
Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to https://192.168.78.4  again. If this error persists, it is possible that this site uses an unsupported protocol or cipher suite such as RC4 (link for the details), which is not considered secure. Please contact your site administrator.


Please help..thanks

Did you change any of the default ports on it when you set it up? Such as the HTTP Port?

This is due to old frimare and RC4 cipher.

Login with IE.
after login change main.html into diag.html
e.g. https://192.168.168.168/diag.html

find the enforce RC4 cipher. Disable this check box, this will trigger a reboot.

one quick question, how do I connect to the box now? Via management port?  
If that is the case, do I use the new lan ip or default?  which is 192.168.1.254

thanks

but you can also do this on 192.168.78.4

just use IE. IE still accepts the RC4 cipher.

yes, use Internet Explorer.

As I said, the error is due to that firmware enforcing RC4 cipher. Chrome and Firefox no longer accept that cipher.

other option is boot to safemode and upload the latest firmware 6.2.5

That's it. I found an old XP laptop in the office that has not been turned on for at least 3 years.  I used IE to log in and unchecked it.  Thank you very much
