Error 1001 - DNS resolution error

Hello!

I get this error often when I try to access various websites. This doesn't happen when I use Opera, so I assume the problem is not with the websites.

My OS: Windows 10. My Firefox version: 127.0 (64-bit).

Thanks for looking into it!

"What dns settings are on the computer and router?" I don't know but could that be an issue if everything works fine in Opera?

I just noticed something:

If I type beholder.hu in the URL bar I'm taken to the Error 1001 page.

But if I type https://www.beholder.hu/ it works.

It turned out that I manually set a proxy server some time ago and I forgot about it. I've disabled it and now everything seems fine. Thank you jonzn4SUSE!
