Please redirect me to the correct forum if needed.
HTTP POST requests are getting timed out. GET requests are working fine.
The problem is specific to few sites eg Quora, Lumosity, Paytm, AskUbuntu
To make things worse, only few pages on these sites have problems. Login page on lumosity, upvote button on quora, checkout button on paytm, post question on askubuntu etc.
I tried with Firefox, Opera, Chromium, Arora, Midori, Epiphany, cURL, wget
They are working as expected with Midori, cURL, wget but not other browsers
I even tried Ubuntu 14.10 and Ubuntu 15.04 (Things are working fine on Windows) I have re-formatted my entire system. So every thing is configured with default values
I am not able to find any common denominator. Please help

After some debugging with Wireshark, I finally resolved my problem by decreasing mtu
The command is
sudo ifconfig eth0 mtu 576
