Can't sign in through Github (OAuth)



Ever since being bought by AWS, I can’t sign into C9 through my Github account, which is the only way I know of to access my account.

If I am not signed into Github, I am redirected to the Github login, which I complete successfully, then it just redirects back to . If I am already signed into Github, pressing the Github login simply redirects back to .

If it means anything, there are some errors in the JS console:

profile.js:24870 GET 502 (Server Hangup)

Failed to load No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘’ is therefore not allowed access. The response had HTTP status code 502.

profile.js:28915 Uncaught TypeError: Cannot assign to read only property ‘NONE’ of object ‘#’

Cross-Origin Read Blocking (CORB) blocked cross-origin response with MIME type text/html. See for more details.


I think I’ve pretty much resolved it. My account is blocked and attempting to sign in through OAuth causes this to fail silently.
