I am misreading the packet trace.  Please disregard my statements about packets and fragments.  Sorry for the red herring.

Hmm.  In the not-loaded file the web server is definitely replying.  One thing that looks weird is that the webserver is replying with giant TCP packets consisting of many fragments.  It appears to work, but my understanding is that the packet size should be below MTU.
By huge you mean 1514?

I am also seeing some bad checksum (with bad value, not simply offloaded 0x0000).

I have encountered similar problem few weeks ago, but I did not solved it - it stopped hapenning when i stopped sending small chunks of data (i use netconn_write without oversize enabled, so i just added another buffering layer to stop sending super short packets occupying whole pbuf each).

Reported packets sizes were similar so it might help :/
