502 Proxy Error - PUT request to MDM OSX Server via apache ProxyPass on ubuntu 14

I am trying to set up a OSX Server behind an ubuntu server with apache2 and vhosts which uses proxypass to send requests to my OSX server. Most request work like they should but I am unable to make the put request work, I get the following error. This is result is via curl but it says the same thing. > The proxy server could not handle the request PUT > /devicemanagement/api/device/mdm_checkin This is the command I used > curl -k -X PUT > "https://mysupercoolserver.xyz/devicemanagement/api/device/mdm_checkin " -d > checkin-data.plist The following is my vhost configuration ServerName mysupercoolserver.xyz ProxyPass / http://10.0.1.40/ ProxyPassReverse / http://10.0.1.40/ ProxyPreserveHost on Require all granted ServerName mysupercoolserver.xyz SSLEngine On SSLProxyEngine On ProxyRequests Off SSLProxyCheckPeerCN off SSLProxyCheckPeerExpire off SSLProxyCheckPeerName off SSLInsecureRenegotiation on SSLProxyVerify none SSLVerifyClient none SSLCertificateFile /etc/ssl/mysupercoolserver_xyz.crt SSLCertificateKeyFile /etc/ssl/mysupercoolserver_xyz.key SSLCertificateChainFile /etc/ssl/mysupercoolserver_xyz.ca-bundle ProxyPass / https://10.0.1.40/ retry=1 acquire=3000 timeout=600 Keepalive=On ProxyPassReverse / https://10.0.1.40/ Timeout 2400 ProxyTimeout 2400 ProxyBadHeader Ignore ProxyPreserveHost on Require all granted ServerName mysupercoolserver.xyz ProxyPass / http://10.0.1.40:1640/ ProxyPassReverse / http://10.0.1.40:1640/ ProxyPreserveHost on Require all granted ServerName mysupercoolserver.xyz ProxyPass / http://10.0.1.40:2195/ ProxyPassReverse / http://10.0.1.40:2195/ ProxyPreserveHost on Require all granted **Is there anything I can change here to solve the issue?** https:// works for downloading the profile and certificate and I know the other ports work as well since requests are going through.
