Wifi Captive Portal Not Launching on Opera GX

I have been using Opera GX as my default browser for almost 5 years and have consistently faced the issue of being connected to my institute's wifi, but the wifi captive portal just refuses to launch.

The only thing that seems to work is temporarily switching my default browser and logging in via Chrome, and then switching back to Opera.

While using Opera, when I click on the "action needed to connect" prompt, an MSN redirect page pops up, but it immediately fails to load, giving me a "no internet" or "DNS address could not be found" error. Sometimes, I don't get the prompt at all. Sometimes, it says I am connected and have internet, but nothing loads.

I have tried the following things to no avail:

Forcing the login page to launch using the IP address, login web address from Chrome, http://clients3.google.com/generate_204, and http://neverssl.com (again, it just says "no internet" or "took too long to respond")
Disabling all extensions (though none of them are related to internet connection anyway)
Disabling "always use secure connections" (the login page sometimes shows up as insecure even in Chrome)
Changing the DNS-over-HTTPS settings.

I used to think this was an issue with my institute's wifi and not Opera, but I am currently in a different institute and am still facing the same issue. Can't seem to find any viable solution online either.

Opera Version: Lvl 6 core 119.0.5497.78
System: Windows 11 64-bit
Chromium Version: 134.0.6998.205

Changing the DNS-over-HTTPS settings.

You might have to have DNS over HTTPS completely off at the URL opera://settings/system.

If you're using a VPN in Opera or outside Opera, you might have to have it off initially.

If you're using any custom DNS settings for Windows (in the TCP/IP settings for the network connection in question), test with "Obtain DNS server address automatically" instead for a while to see if it makes a difference.

In Settings -> Network & Internet -> Proxy", test with "automatically detect settings" in the opposite state that it's set now.

It could be security software like Kaspersky or Bitdefender or NordVPN affecting only Opera.

You can try regular Opera (Opera One) to see if there's any difference. You can see what Vivaldi, Brave and Edge do too. It could be an issue with Opera GX, but not sure.

I see https://www.comparitech.com/net-admin/fix-msftconnecttest-redirect-error/, which kind of sounds like your issue.

I see Apple devices use captive.apple.com

Some users have said type 8.8.8.8 in the address and pressing enter can trigger a captive portal page.
