Unable to receive response for big payload size

I have got a apache http server which is deployed on openstack provisioned resources. Somehow whenever my response has a large payload I am unable to receive the response to my web browser. I am using LBAAS from neutron and use the IP of LBAAS to hit apache http server.

Scenario1: I send a request for an html file which has the size greater than 1178. I do not get any response back instead I get 504 error code. Scenario2: I send a request for a html file which is less than 1178. This time I get back the response.

To summarize all the communications are working fine, only difference between the 2 scenarios is payload size. I have been playing around with MTU on network as well as the compute node for br-tun and eth1 but till now have not succeeded . I am also trying out few things with tcpdump but nothing substantial I have found till now.

Need some help on how to debug this out.

The issue got resolved by increasing the MTU of GRE tunnel.
