It means your phone and your computer are unable to connect. Make sure they are on the same network, that the network is not restricted and that your port 8083 is not in use by some other program.
I have the same problem. After I installed Mendix 9 ( beta) , i can’t run my Nativ App on Make it Nativ with version 8.18.
What I’ve done so far:
-Deinstall Mendix 9
- Deinstall and then install Mendix 8.18 again
-Change port several times
-Both phone and computer are on the same network
- Deinstall and install Make it nativ on mobile
-Restart my PC several times
I have faced this error before , but everytime when I restart my pc it works fine, i don’t know whats wrong this time. Any suggestions?
