Hi,
Using Firefox Quantum 63.0.3 on Win 10 Pro I can't access NatWest Online
Banking. I get the following message.
"Secure Connection Failed
The connection to the server was reset while the page was loading.
The page you are trying to view cannot be shown because the
authenticity of the received data could not be verified."

I was able to access the site last week with no problems.

Other banking sites are unaffected.
I can access the site using Chrome.

any ideas as to what the problem might be?

cheers,
Iain

The clue may be in your (non-compliant) signature, try disabling avast's
https scanning feature

Thanks for the respons Andy, I had forgotten that Avast has a habit of
reinstating The email signature when it updates. Hopefully, I've
disabled it again. I've turned off the https scanning but it has made no
difference. The problem persists.

Was that the full message you originally posted, or was there an
"advanced..." button showing more information? or letting you view
certificate details or add exceptions?

Oddly enough, it is usually Chrome with which I find this problem from
time to time.

When it happens, I need to delete all cookies and local storage related
to nwolb.com, and after that I can get in ok again. So maybe you need
to try something similar in Firefox?

But I think it boils down to something poorly implemented at the NatWest end.

Cheers
Tony

No, but you are not alone. I am now getting that when seeking to log in at

https://www.nwolb.com/default.aspx

with Firefox (as yours).

But not in other browsers.

The login page is OK for me, but I no longer have a natwest account.

Check your browser's TLS config, at SSLlabs
https://www.ssllabs.com/ssltest/viewMyClient.html

does it allow TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384?

Thanks.

I have the NatWest login page back now so probably was a problem at
their server. But for the record the test (once I enabled allowed the
inevitable scripts) showed green "Forward Secrecy"
