I'm having the same issue. It works on my company laptop (uses VPN so different DNS) and it works on my cellphone (same DNS). On my desktop It works with a VPN (incognito mode in Opera) but doesn't work with Chrome, Edge or Opera w/o VPN. It does work in Vivaldi w/o VPN. I can resolve the ip on all devices and receive back the same ip. Any help would be appreciated.

New find... I ran Fiddler to see if something was getting blocked, and with fiddler up... there are no issues. As soon as fiddler isn't capturing traffic, the issue comes back. Does anyone have any ideas?

Im having the same issue as well, I was trying to get sync working between my laptop and computer so I reinstalled operaGX on laptop and got it connected to my account no issue, but when I tried to connect my desktop computer i get the error message when trying to open the page. It also works on my phone without any issues, I'll try to see if reinstalling or anything might fix it.

Looks like turning on the built-in VPN and then trying to go to synchronize and it works.

@leocg the VPN speed is pretty slow but I did see that works. The problem with thinking it is isp is it works on my cell when on wifi. It has to be something on my desktop. But I think I am going to go with another browser. Will try back when the new browser makes me angry lol.

I only turned on the built-in vpn for turning on sync then turned it off, if you want to try that.

With the VPN turned off, if you goto the URL
opera://settings/system, enable DNS over HTTPS, and restart Opera, do things work? If so, are you sure your Opera is up to date? What version do you have? Seeopera://about.If that works for Opera, maybe there's something wrong with your DNS settings on your system since other browsers have the issue too. You might want to check for malware too just in case.
Note that some ISPs in Egypt, Bangladesh, Nepal, Jordan, and the Philippines are known to block opera.com and its subdomains. If you're in one of those places, that could be the problem. However, in that case, you shouldn't be able to reach any opera.com site at all and you shouldn't get far enough to even get a server error.

@burnout426 so I viewed the status and it works. As long as I log in through the VPN all is good it appears. Thanks for the help guys

Does that site use https? (Should be.) Did you allow fiddler to decrypt traffic? If yes, then something may be wrong with certificates or security protocols - fiddler uses it's "faked" cert to make browser believe that site is actually what it claims be and connects to real server a bit differently.
If you used http or didn't allow fiddler to decrypt traffic, then I have no idea.
Do you have any proxy set in (Windows) Internet options? This can behave differently with fiddler too.

@donq yes it was when I decrypted traffic. I found it could be a cert but couldn't find anything obvious.bi also find it strange other people have this issue too. Either way.l, if I log in through a VPN it seems to sync. I'm good with that at this point lol

@donq I am still interested in trying to fix the problem without having to resort to the VPN, it is very odd cause it has always worked then suddenly stopped one day and requires VPN. It works on other devices on the same network I believe, only on my PC it seems to block or not recieve any signal from the website.
What should I do in order to diagnose the issue? Cause most of what has been said so far has gone over my head. -

@davis1232 I think don't is right about the cert thing. When I was showing a guy at work that fiddler fixed it he thought cert too, but I'm not a network guy so not sure how to track that down

Sorry, I can't help here
I'm in no way a security/network expert.I could suggest to compare all this protocol handshake in fiddler with and without decyption (alhtough without decryption you likely can't see much), maybe you can see someting under Opera dev tools network tab (or not), maybe you could search for security related events in Windows event viewer (you may see some SSL errors there - but not always), you could analyze cert contents (Opera auth server vs Fiddler "fake" one); maybe you could configure some aspects of Fiddler SSL/TLS connection etc - a lot of guesswork.
Most likely this is some problem with chipers (client and server can't properly understand each other) and Opera auth server improper handling of some SSL/TLS protocol properties - but even if I had same problem here, I'm not sure that I could find real cause of troubles.
Have you filed Opera bug report?
