  • Node (npm) Version: 9+
  • IRI Version: v1.4.2.1

Aerowave#5383 is reporting the same Issue on discord:

Aerowave - Today at 6:57 AM Hi, I'm having an issue with Nelson this morning, similar to @Typpi ... after connecting to IRI Nelson terminates with an unhandled promise rejection. Nothing's changed on my config recently, only rebooted the server this morning, now it won't find any neighbours again? Thanks in advance

Contact:

Contact me on Discord at Typpi#3906 or email at [email protected]

Thanks!

You have triggered an unhandledRejection, you may have forgotten to catch a Promise rejection:
