I think doing a clean Windows reinstall from USB would be the best solution (the reset feature in Windows tends to leave drivers in latest state which can be a problem). Back in the Win9x days it was annoying because reinstallations took hours. Now you can be done in 1-2 hours doing a clean Win10 install with almost guaranteed success because I see no reason why this should be exclusive only to Opera.

But at least THIS problem of mine is solved --- in the most banal way possible. Should I be happy or scared?

"C:\Program Files\Opera\launcher.exe" --no-proxy-server

to see if that makes any difference.

After 1803 and 1809 windows update opera dont load web pages but edge browser works fine .If I return to windows before 1803 build opera works fine again.I did a clean install of 1809 and I have turbo off and automatic proxy address on without vpn services on.I run genuine windows 10 pro 64bit.Any ideas?

this part you said (and I have turbo off and automatic proxy address on without vpn services on.)
do ya mean this.. if not nevermind the rest..

when ya go here..

r u typing in the public proxy addresses manually..

Are ya use 'n public proxy addresses.. if so

sum work for a bit but mostly they work only for a very short time..

thats why in your 3rd post

opera version is 56.0.3051.36 (latest).I don't have any 3rd party anti virus just clean install windows 10 pro to find out why is that problem persists.I tried without any firewall or defender on also..no luck.Sometimes opera can load pages for a few minutes then struggles to open them and stops.

this part you said (Sometimes opera can load pages for a few minutes then struggles to open them and stops)

maybe try different proxies

Wondering if the 32-bit version of Opera works any differently.

Wondering if right-clicking launcher.exe and the latest opera.exe and changing the compatibility makes any difference.

Wondering if uninstalling and reinstalling all network adapter drivers fixes things.

Wondering if messing with the default browser settings has any effect. For example, set Edge back to the default and then set Opera to the default. Would be weird if this helped, but I'd try it.

Wonder if purposely installing a VPN program, using it and then uninstalling it might somehow fix the problem.

Wouldn't help with a fresh Windows install though as those wouldn't be installed, unless one installed some driver for one of their devices from disk or the net and that installation installed one of those also.

There's opera://flags/#network-service-in-process. I don't know what it does specifically beside what the description says, but you could give it a shot to see if it makes any difference.

Also, maybe testing the connection with Wireshark might reveal how far Opera gets, which then might lead to cause.

yes i formated my c drive (no old windows) and run windows 10 instalation from usb drive..about 5 times already
I tried firefox portable and runs fine also...weird

looks like the win updates may be the culprit..

but

can ya see if ping work.. Launch a command prompt and type ping www.google.com or what ever ya wanna

You should get the return pings within a short period..

dont worry if ya already started burnouts last suggestion..

.I did a clean install of 1809

As in, you went to https://www.microsoft.com/en-us/software-download/windows10, downloaded the tool. created installation media (USB Flash drive for example) for Windows 10 Pro 64-bit (or whatever you have), restarted your computer, booted from the USB stick and installed Windows fresh (no upgrade etc.)?

If not, I'd do that. If so, I'd recreate the installation media and try once more just for good measure.

the reason i mention "WLAN autoconfig" is cos ya said when ya go back to before - 1803/1809 build opera works fine again..

ok - so this Note from Microsoft - We have paused the rollout of the Windows 10 October 2018 Update (version 1809) for all users as we investigate isolated reports of users missing some files after updating..

The Windows Service called "WLAN autoconfig", and its description
says that it runs the - "WLAN Service" = which sets up the LAN connections..

Apparently, this service looks for the folder - C:\ProgramData\Microsoft\Wlansvc

i think this address must be hard-coded coz

(a) it is not n e where in the registry, and please - note (B) esp..

(B) if you simply move it, all wireless LAN functions stop completely !

so when ya move back to the 1809 it perhaps moves - the Wlansvc folder or maybe it gets deleted.. and or the service - "WLAN autoconfig" - gets disabled.. or sum other services could get disabled sum how.. ya could check sum

Note - everyone should back this folder up C:\ProgramData\Microsoft\Wlansvc for safe keep 'n *seriously..

ya said new profile doesn't help. so try burnout426 suggestion too..

i dunno if this will help..

if you're use 'n wireless..
make sure this service - WLAN AutoConfig - is run 'n & set to Automatic..
