Do more on the web, with a fast and secure browser!

@burnout426 Thanks! I created a new user account and installed Opera. I had previously tried to uninstall and reinstall using my own account but that had failed.
In the new account I was able to browse successfully.
Returning to my own account I continue to have the same problem in Opera, DNS_PROBE_FINISHED_BAD_SECURE_CONFIG
@jonwatson I think the problem is related to DNS.
When "Use DNS-over-HTTPS instead of the system’s DNS settings" is OFF the error changes to: ERR_CONNECTION_RESET
@burnout426 Thanks for the ideas!
@burnout426 Thanks!
Meanwhile I had installed "Windows Firewall Control" and manually allowed programs as it blocked them.
It now says these are allowed:
C:\users\jon\desktop\opera.exe
C:\users\jon\appdata\local\programs\opera\opera.exe
Standalone install works perfectly, allows normal browsing.
But upgrading my existing installation returns for every web page:
DNS_PROBE_FINISHED_BAD_SECURE_CONFIG

Chrome has always run well on my desktop PC.
In 2021 I installed Brave and used it for several months until suddenly every web page gave the following error:
"This site can’t be reached The connection was reset."
Note that this is essentially the error that I now see with Opera. I tried every suggestion that I could find by googling but nothing helped. So I went back to Chrome.
On 3/2/2024 I installed Opera and it worked great. I kept several open Opera windows with multiple tabs.
On 3/15/2024 I ran Windows Update and restarted Windows. Immediately and since that time Opera cannot reach any web page.
Chrome and Edge still work fine.
For almost every web page, Opera displays:
This site can’t be reached
The connection was reset.
and also:
ERR_CONNECTION_RESET
One web page is different.
It may have been the last youtube that I had started watching:
https://www.youtube.com/watch?v=MiogoWwpu3E
For this one Opera displays:
Connect to the internet
You're offline. Check your connection.
Another different message happened when I mistakenly typed "appdata" as the address in Windows Explorer (file not internet) and got a different error:
This site can’t be reached
Check if there is a typo in appdata.
Try:
Running Windows Network Diagnostics
Changing DNS over HTTPS settings
DNS_PROBE_FINISHED_NXDOMAIN
So I enabled DNS over HTTPS in Opera using Cloudflare. No change.
So I ran:
ipconfig /flushdns
ipconfig /release
ipconfig /renew
No change.
I just uninstalled and reinstalled Opera. No improvement, for example:
This site can’t be reached
duckduckgo.com’s server IP address could not be found.
DNS_PROBE_FINISHED_BAD_SECURE_CONFIG
Why post such a bug report? There is little that Opera developers can do except send me questions.
But maybe somebody somewhere has had a similar problem and found a workaround.
