Hi Benjamin,
You have to access directly the Apache (or nginx) port, not the fastcgidispatcher one . For example :
Host : localhost Port: 8080
connector: gas
But beforehand you need to allow the GAS to send the version to Genero Studio :
<INTERFACE_TO_CONNECTOR>
<SEND_VERSION>TRUE</SEND_VERSION>
</INTERFACE_TO_CONNECTOR>
And authorize access to GAS monitor . For example :
<MONITOR>
<ALLOW_FROM>ALL</ALLOW_FROM>
...
</MONITOR>
Best Regards,
Lionel
