Gmail is having authentication problems. Some features may not work

Question

I am writing a Chrome extension that sends voicemails from Gmail Web App with Gmail API.

I keep getting this red message somewhere around the time that I try to authenticate a user.

My questions:

• Why is this happening?
• Can I somehow download Google Javascript Client library in a way that it doesn't create a global gapi variable?

PS. I already tried reading the documentation. Also, the extension works fine, and Gmail works fine, the red message is the only problem.

Solution 1

For the people who are directed here via google search (which I used to), check your extensions. After I research so many hours, I see that one of my extensions is modifying my header, disabling it resolved the problem.

Solution 2

Mine was due to --disable-web-security flag.

Solution 3

Mine it was because I use header changer plugin in chrome.
Just disable the plugin and everything goes well.

Solution 4

I Don't know if this gonna help you, but I am getting the same error when I enabled this Option at Safari: Developer -> Disable Cross-Origin Restrictions.

I re-enabled it, clicked at login link and the problem has gone away.

Have you considered that this may be a transient problem? For how long have you been getting that?

[Vlas Bashynskyi]

@Xan, the problem has been around for a few weeks. It appears only when the extension is running.

Well then, I'm afraid this question might be in the "can't tell without seeing your code" category.

See a related discussion, try the suggestion to inspect network traffic.

if you added the flag("--disable-web-security") to the Chrome shorcut will show this message. removfe --disable-web-security flag from the Chrome launcher icon

Yes, this was an issue with a chrome extension I was developing.
