It would be beneficial if the Sync Protocol Log would reflect a (un)successful login attempt. If I sign in with a wrong password, I get the same error as a correct password - "An Error has Occurred .. Please try again", Perhaps detailing what the error is would be beneficial.

Thanks

@rlh1533 - I have no issues signing into sync with v39 .. Did you try to log into the web site "auth.opera.com" or "sync.opera.com" to verify your login credentials?

Nothing to speak about .. The About tab has a lot of "Uninitialized" and the other tabs are empty ..

I just downloaded Opera 39 on the Mac and have no issue signing into sync. So it's something related to the v40 beta

So .. Clicking on Sync Sign in, Instead of logging in with my credentials, I created a new account .. and viola, I was logged in. Then I thought that it was a special character in my password (contained '{'), so I changed my password to remove special characters and still not able to sign in. Weird .. I'm going to delete my login and in 7 days will attempt to create it .. We'll see how that goes.

But something in the beta is ... If I give a timestamp of a log in attempt, can the server side be looked at for a possible reason?

Version: 40.0.2308.3 - Opera is up to date
Update stream: beta
System: Mac OS X 10.11.6 64-bit

I disabled all my extensions .. When I sign in it now says "An Error has Occurred .. Please try again". This does not occur on non-beta versions.

Found this on the Developer v40 change log from July .. I didn't see it in the Beta v40 change log .. Could this be the cause?

The first Opera developer 40.0.2267.0

"Right at the start of O40 cycle, we are introducing an upgrade to the synchronization feature. Following the industry standards, we have changed our authorization infrastructure to support OAuth2

It seems when I click the initial Sign In from Preferences (which brings me to the sign in window) is when I get the above error .. When I click Sign In to actually sign in with my credentials I receive no errors in the log

Could this be related to:

Upgrade to the synchronization feature. Following the industry standards, we have changed our authorization infrastructure to support OAuth2 ??

I am seeing about 60 of the following message in the Mac Console when I attempt to sign into sync

8/5/16 11:55:14.486 AM Opera[34583]: Error: this application, or a library it uses, has passed an invalid numeric value (NaN, or not-a-number) to CoreGraphics API and this value is being ignored.Please fix this problem.

No error message .. The Sync Menu icon appears for about 5 seconds then disappears. Preferences shows that I'm not logged in. I cross posted this to the Beta forum as I'm not having an issue on non-beta versions. Thanks

I upgraded today v40 (Mac 40.0.2308.3) and seems I cannot sign into Opera Sync. When I sign in, the sync icon appears for 5 seconds in the menu then disappears, but preferences for sync still shows that I am not logged in. Login credentials verified by logging into the Web site (auth.opera.com). Other platforms (non-beta) do not have an issue.

I upgraded today v40 (Mac) and seems I cannot signin for sync. When I signin, the icon appears for 5 seconds in the menu then disappears, but preferences for sync shos that I am still not logged in .. still shows the "Sign in" button.
