Expected behaviour

Unsure

Actual behaviour

Sometimes this causes Nelson to stop finding new peers, other time it seems to not cause any direct problem.

Steps to reproduce

Currently running a network of 12 Nodes, This error is appearing on almost all of my nodes. Followed Guide for install on the github page. Im also running nelson under PM2 with my own config. (Can provide config if needed)

Basic Info

Operating System: Linux Ubuntu 16.04 LTS
Node (npm) Version: 9+
IRI Version: v1.4.2.1

Aerowave#5383 is reporting the same Issue on discord:

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!
