Redmine

I have been recently trying to configure Redmine passenger 4.1.1 and 4.1.0 docker image to work in a suburi following documentation at

https://www.redmine.org/projects/redmine/wiki/HowTo_Install_Redmine_in_a_sub-URI#section-11

It does work but just 50% of time. First request to redmine suburi returns whole site perfectly however next one result on a "RoutingError (No route matches [GET] "/xxgaseosa"):". Subsequent request result on the same behaviour.

Does any one know what´s wrong?

Here some output from log:
