Bangles JS 2 won't connect via Gadgetbridge Bangle

I'd try:

• Make a backup in Gadgetbridge to keep data safe
  
• remove the Bangle.js from Gadgetbridge
  
• in android bluetooth settings 'forget' the Bangle.js
  
• in Gadgetbridge try adding the Bangle.js anew.
  
  

Edit: Can you still connect to the watch in other ways, e.g. with web bluetooth in a browser. On some other phone or on a computer?
