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?
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?
