ORDS, SODA & JSON in the Database

Hello guys,

I am having problem with my apex application.
I get ERR-7621 Could not determine workspace for application (:) on application accept whenever I try to upload any file to wwv_flow_files table. Other things work fine.
Anything larger than 300Kb fails.
This only happens when connected via internet(https), doing it locally works fine.

I am using Apex Listener on Tomcat.
Uploading via Modplsql address works fine so it is something to do with the listener but I can't figure out why and it is driving me nuts...
I have searched the net but found no real solution yet.

These are my settings
Apex Listener instance named "apex" deployed in Tomcat in machine01
Tomcat running on machine01
DB and Apache running on machine02

httpd.conf
ProxyPass /apex http://machine01:443/apex
ProxyPassReverse /apex http://machine01:443/apex

tomcat server.xml file connector setting
<Connector port="443" protocol="HTTP/1.1"
proxyName="machine02"
scheme="https"
proxyPort="443"
secure="true"
URIEncoding="UTF-8"
maxHttpHeaderSize="32767"
connectionTimeout="30000"
redirectPort="443"

noCompressionUserAgents="gozilla, traviata"
compressableMimeType="text/html,text/xml,text/plain,text/css,text/javascript,application/xml,application/css,application/javascript" />


Can anyone help me please?
