When I try to run Shinyproxy behind a apache2 proxy, i always get the following error:

My apache config is the following:
RequestHeader set X-Forwarded-Proto https
ProxyPreserveHost On
# Maps remote servers into the local server URL-space using regex
ProxyPassMatch "^/(.+)/websocket" "wss://localhost:8080/$1/websocket" keepalive=On
# Maps remote servers into the local server URL-space
ProxyPass / http://localhost:8080/
# Adjust the URL in HTTP response headers sent from reverse proxied server
ProxyPassReverse / http://localhost:8080/
ProxyRequests Off
Sometimes when I access the site as first user, the application loads as expected. But when I try to access the same app with a second tab or computer, the above error is raised.
Thank you for any help in advance
