Hi gchearn@gmail.com, thanks for the report. Could you follow the instructions at https://sites.google.com/a/chromium.org/dev/for-testers/providing-network-details to get an net-export dump?
Thank you.

Sunji,
  Attached is the net-export dump you requested.  If I did it incorrectly

Hi Guy Hearn, I am not seeing the net-export dump. 
Could you go to https://bugs.chromium.org/p/chromium/issues/detail?id=719496, and  attach the net-export log using "Attach a file" in a comment?

Thanks.

Xunji,
  Hope this is the file you need. I thought it was in the last message I sent.

One last thing you could try is to go to chrome://extensions and disable AdBlock. There are a few requests in the log that were blocked by AdBlock.

Xunji...,
  Disabling my AdBlock apps didn't work. I tried several other steps which
got it working, I'm not sure which one worked, I tried several at once. The
steps I tried were: enabling 3rd party cookies and disabling do not track
extension. I don't like either solution so I'll try to narrow it down. I'm
sick of this issue for the moment so when I get around to it I'll let you
know which step was the correct one.
  Thanks for your time in addressing my problem.

Guy Hearn

What worked was disabling Adblock, AdblockPlus,and DoNotTrack extensions.
In addition I had to enable third-party cookies. I don't like doing any of
these steps.

Guy Hearn

Thanks for confirmation! 

This issue appears to be caused by interaction between extensions and particular browser configuration, and not by a bug in the browser, so there is nothing to fix.

Thanks for your patience!

Hey mef,
  Perhaps nothing to fix in browser but others with the same configuration
and extensions might like to know how to make amc.com work as I showed in
last message.
  Issue ended.
