Hello guys,

Many thanks for your interest in the project.

~~@sokoow : Your issue seems to be a bug fixed in v1.6-RC1. If you are using an older version you can~~

~~Upgrade the Træfik version~~
~~Or edit your acme.json file to add {}.~~

@tha80, @timothyallan, @nathanaherne : The error message appears when the acme.json cannot be opened by Træfik. Can you provide your entire configuration (Træfik options and Docker) in the way to reproduce the issue?

~~Thanks in advance.~~

EDIT : Issue reproduced, fix is coming ASAP.
