Chrome 55 WebGL Issue

I have a small Unity app that runs fine in Firefox and Safari. It even works with ‘build & run’ when I run locally with Chrome 55. However, when I upload the WebGL project to a remote Apache server, I get the following error in the Chrome 55 console after the loading finishes:

Invoking error handler due to
Uncaught abort(102) at Error

If this abort() is unexpected, build with -s ASSERTIONS=1 which can give more information.

What is the meaning of this and how can I get my app to work in Chrome?

Do you get a full callstack (possibly from a Development build)?
