http: proxy error: context canceled

With the latest couple of version, we get a lot of these errors:

fabio | 2017/07/06 14:58:15 http: proxy error: context canceled
fabio | 2017/07/06 14:58:16 http: proxy error: context canceled

These are requests from visual studio polling a nuget server for updates by the way.
The complexe flow:
visual studio -> fabio -> haproxy doing an url rewrite -> nexus repository manager.

We run fabio in a docker container.
We have these errors with any version later than 1.3.8-go1.7.5
With 1.3.8-go1.7.5, we don't have this problem.
If I add a haproxy in front of fabio, I also don't get this error.
We're not using SSL.

Anyone got any idea if this can be caused by a go bug?

Same problem.
I try to add a route like :

route add new_service xx.domain.com http://a-new-url.zz.com

Fabio log :

2017/09/27 14:21:34 http: proxy error: context canceled
2017/09/27 14:21:34 http: proxy error: context canceled
2017/09/27 14:21:34 http: proxy error: context canceled

Can you post your runtime config?

[tbouvet]

+ service-a service.production.mydomain.com/ http://192.168.100.10:80/ 
+ new-service service.mydomain.com/ http://service.production.mydomain.com

[magiconair]

on which route is fabio causing the error? Is that reproducible? Do you have write or read timeout set in the config?

[tbouvet]

The error is when I test http://service.mydomain.com .
My simple config :

proxy.addr = :9999,:443;proto=tcp+sni,:1234;proto=tcp
