Gadgetbridge cannot find Bangle.js

What phone do you have?

The Hisense A5, an e-ink smartphone that recently came out in China.

Could you maybe try removing the watch from Gadgetbridge, and trying again without choosing to pair when prompted?

I just tried it. We shall see. I didn't even know that was possible to connect without pairing. I'll post again in later today if this resolves the issue.

If you have Android this might be the battery optimization.

I actually did go into the optimization settings and removed Gadgetbridge, and simply forgot to mention that in my earlier post. Thanks for bringing it up, though, as it's an important point to mention for others with a similar issue.
