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

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  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

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

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
