Symfony 3/FOSJsRoutingBundle: not allowed to access router.js

Question

I'm trying to install a Symfony 3.1.4 project on a managed server. It works perfectly on my local machine, but not on the external.

For JS routing I use FOSJsRoutingBundle, version ^1.6.

Problem:

When I visit http://mydomain.tld, the browser tries to load http://mydomain.tld/bundles/fosjsrouting/js/router.js, but is not allowed to: 403 Forbidden.

For my understanding the file exists, but I'm not allowed to load it.

Solving approach:

• php bin/console cache:clear --env=prod
• php bin/console fos:js-routing:dump
• php bin/console assets:install --symlink web
• chmod for web/bundles/*: 755

Nothing worked.

Could it be related to the symlinks? I'm a bit lost and. Any ideas?

Thanks in advance!

I recently had this issue and this is what worked for me in Symfony 3.4:

In config.yml, you need to add a package to the assets config with the base_path set to /bundles. This makes the route public and should allow you to pull any asset file from any bundle installed. Of course, you can instead add a package per bundle if you wish to do so.

config.yml

framework:
    assets:
        packages:
            bundles:
                base_path: '/bundles'
