The support person at the hosting looked at the issue and reports:
"I reviewed the issue, there is no problems with the "configs/routing.yml" files, the paths in this file are correct and only route "operator/login" "/chat" as indicated by the application.
The .htaccess configuration for Apache is also not causing the issue, so the problem is occurring somewhere in the backend of the site configuration. I am was not able to find where these settings would be located as I am not familiar with the site code."
