Windows 7: Opera 12.17 suddenly not working with SOME https sites

19 Oct 2014   #11

Windows 7 64 bit

Callender - I tried your site and got RC4, 128 bit so ok there.
With a port viewer (I use Nirsoft CurrPorts but tried opview but made no difference) all Opera remote ports are but Kaspersky shows port 443 connections to remote host so all getting routed to Kaspersky THEN to the website via 443 so effectively the same thing.
Not sure where your security prefs pic comes from. I Use Kaspersky Internet Security 2013 suite.

I have used Chrome but hated it plus it causes a whole range of other issues ranging from email to HTML association screw ups through to non-working hyperlinks in XLS's...
Major PAIN to try and fix.

Just noticed - Google no longer redirects to the https equivalent. Guess they are aware of the problem now ..

Opera 12 - Security Preferences

To get to security preferences type:


in the address bar and press enter.

Scroll down and expand security preferences.

Make sure OSCP Validate Certificates is checked along with the other settings shown in the screenshot in Post #8 in this thread.

However there are even more settings available and you get to them like this:

To enable or disable specific security protocols, from the menu, go to Settings > Preferences > Advanced > Security. Check or uncheck the protocols you want to enable or disable.

If you want to select ciphers to enable or disable, click the "Details" button.

Compare your settings with mine. Those highlighted in red are unchecked - everything else is checked.

On another note it might be wise to follow the general advice given in the link below if you haven't already done so:

How to configure Opera 12.x for safer internet browsing

If it still doesn't work the only other suggestion that I've go is to temporarily disable Kaspersky and try visiting problem sites to see if you can connect. If it works then it's a Kaspersky issue.

RE: Other browsers. I have six browsers (installed or portable) as they all have different strengths and weaknesses. I don't have Chrome but do have a Chromium based browser installed.

Yep to everything ! Same as yours...
Sticking with KIS disable ssl scan option for now until a better fix comes along.
Thanks for the input !

3/11/2014 - still works fine with Google etc now but some sites using https images no longer display those images.

Secure connection: fatal error (1066)
Unable to verify the website's identity (OCSP error).
The response from the online certificate validation (OCSP) server was too old.

Sounds like the sites need to fix their certificates to fix this...

still XP SP3


I had the same problem, with the certificates.
Opera 12.17 and some URL (google, yahoo...).

I forgot that I changed (the day before) the date of the computer to may 2015, and as the certificates are valid from.... to... (before may)

I put the date today (in the interval OK for certificate valid), and everything come OK.
