      I've suddenly started getting this error every time I try to access
      https://uk.virginmoney.com/vmosws/mvmStartLogin.do
      Works fine in Chrome. Have cleared cache. Any suggestions please?

        Goto the URL opera://net-export and turn on logging. Then, goto the site and trigger the error. Then, stop the logging. When you're done, load the log file into https://netlog-viewer.appspot.com/ and see if it says details on what triggered the error.

        Page loads fine for me in Opera.

          Did you mess with any flags in opera://flags? Are you using Opera's VPN? Did you mess with the "Use DNS-over-HTTPS instead of the system’s DNS settings" setting at opera://settings/system?

            Screenshot (267).png

            All the settings you mention appear to be normal defaults, no VPN. This error arose of it's own accord - as far as i know I haven't done anything but it coincided with a browser upgrade which now causes the screen to dim when typing.. The log doesn't appear to say much. Did I do it right please?

              I assume so. You'd have to look at the other categories on the side to see data.

                Hi @simonboyle, and what if you change the opera:flags#enable-quic from default "Undefined" to either "Enabled" or "Disabled" and relaunch the browser, does it helps?

                  Thanks for you help on this. I deleted cache, saved passwords and all cookies and it's now working again but I don't really understand what I did!
