Cant upload Java Application - No name matching appengine.google.com found

[Divya B]

Hi,

I'm using Java GAE, suddenly today I cant able to upload my application using "appcfg.cmd   update \war" command.

I'm getting "CertificateException: No name matching appengine.google.com found" error.

I have also tried to upload the app after deleting .appcfg_oauth2_tokens_java file but not luck. Please advise.

Hi,

It does seem to be an issue related to your server’s certificate being unable to match your host name. By any chance, would you be using a proxy? 

Alternatively, you can test if it works through another network.
