Astrobox not connecting to printer

Have a Afinibot Creality CR-7 will not connect to Astrobox. It has worked previously, but now will not connect.
After reading other connection timeout forum topics, I tried the same settings. No luck.
The connections screen displays “FT232 USB-Serial (UART) IC” but doen’t want to connect.

Below is a copy of the serial.log file contents.
