The requested language "fr" was not available. Available languages: "en, en"

I've got this error

The requested language "fr" was not available. Available languages: "en, en"
406 Not Acceptable - NotAcceptableLanguageException

Got this in my config.yml
jms_i18n_routing:
default_locale: fr
locales: [fr, en, de]
strategy: prefix

I don't know where is the problem ?

[CharlyPoppins]

This problem happens only with www.mysite.com/en/, it doesn't happen with /fr/ ou /de/

[CharlyPoppins]

It seems that the problem come from that jms_i18n_routing: in config.yml can't be override by another jms_i18n_routing: in another config.yml.

I'm not enough expert in Symfony to make corrections.

I have the same issue...

jms_i18n_routing:
default_locale: fr
locales: [fr]
strategy: prefix

[CharlyPoppins]

I'm using this : strategy: prefix_except_default

so there is no bug, but there is no more suffix for fr

monsite.com/fr => monsite.com/

That was not my case, so I keep back my old working version.

There Is a Bug for a long time.
Previously it was not detecting fr_FR preferred language (with undescore).
Now not going to the default fallback and taking 'en'. I think This lib is not really tested.
