The mq-web-console feature's bundles are not distributed in system repo.
Any machine that does not have an internet connection would have to
- download the required bundles and install them manaully
- or create a custom offline repo to install the mq-web-console
It would be good to have these bundles shipped as part of the system repo as this would avoid the issue. The older activemq-web-console is shipped in the system-repo.
A workaround is to use the feature "activemq-web-console" - this is an older version of the web console
