Error retrieving remote device's firmware

This problem just started happening when trying to run a python program on remote device in DigiPython ESP. The device connection is fine in device manager. The program has run without problems before but now it says:

Problem Occurred

'Launching app_name has encountered a problem.

Error retrieving remote device’s firmware.

Remote Device is Connectport X4. Any help greatly appreciated!

see if you can get the remote file explorer working with it (window menu -> show view -> remote file explorer). That’s a good intermediate step to see if the ESP can talk to the gateway. You can also close reopen the ESP and power cycle the gateway. Make sure you’re not autolaunching python scripts too.
