[Solved]SSL and Certificate Error after updating (v44.0.2510.857) Win7*64bit
I updated Opera on 22 March.
After that, following error occurs on some web pages.
It's too difficult for me..
You connection is not private
You attempted to reach www.google.co.jp, but the server
presented a certificate signed using a weak signature algorithm
(such as SHA-1). This means that the security credentials the server
presented could have been forged, and the server may not be the
server you expected (you may be communicating with an attacker.)
You cannot proceed because the website operator has requested
heightened security for this domain.
Opera cannot verify the identity of the server
"****(some page)", due to a certificate problem. The
server could be trying to trick you. Would you like to
continue to the server.
I solved it myself. Thanks guys.
This problem does not occur in Safe Boot + Network.
I checked the event viewer.
After updating, operaautoupdate.exe outputs error.
I checked operaautoupdate.log
Failed to resolve proxy auto config for https://autoupdate.geo.opera.com/ Err: 12180
Recently updated are Adobe, VirtualBox, WindowsUpdate.
So, I tried the following things.
Organize services and startups.
Then this problem was solved.
(I checked antivirus software at the beginning, but it seems not to be the cause of the problem.)
