I tried to run the B4i code of RDC (https://www.b4x.com/android/forum/threads/class-rdc-dbrequestmanager.46568/) after setting up the server as in the tutorial: (https://www.b4x.com/android/forum/t...ation-of-rdc-remote-database-connector.61801/) and after modifying the 'config.properties' file accordingly. The server ran smoothly(B4j and B4i) but as I make the request by Page_click in the B4i code, the B4i log displays (Error response: , status code: 0) ,(Error: Could not connect to the server.) and the B4j displays (Unknown method: batch,Command: , took: 30ms, client=192.168.1.4) then (Unknown method: query, Command: , took: 1ms, client=192.168.1.4). I made sure that the server ran correctly by (http://127.0.0.1:17178/test) and displays (RemoteServer is running (08/12/2019 00:14:30) ,Connection successful). What could be wrong?
