The first step is to be able to access the test page. If it is not working then the IDE will not be able to connect to the Mac. The IDE settings are not relevant.
Can you ping this ip address from the command line with ping <ip address> ?
yes, the ping command is successful. connecting to port 51041, but the connection is cut off immediately. there must be a problem originating from the server application(b4ibuild).
mac server works well. but as there is a shortage in the program. I do not know how good for you, but if you want I can send information via TeamViewer Mac.
