Hi Phani,
I'll carefully look at the logs in the next days: unfortunately nothing seems to be wrong at first glance except that your error is still there.
In the mean time, could you make the last effort on your side to exclude any (HTTPS) issue between your server, curl and your proxy?
$ curl -v https://accounts.google.com -x <proxyusername>:<proxypassword>@10.129.168.48:800
The output from one of my Linux servers (curl -v https://accounts.google.com -x matteo:password@127.0.0.1:3128) looks like:
* About to connect() to proxy 127.0.0.1 port 3128
