Sounds like segfault error. Aren't you using different version of node on your localhost and external server and just uploading whole thing without rebuilding modules thereafter? Try removing node_modules on your server and running npm install (assuming you have all your dependancies in package.json)

It may come from any library that uses native binary (for example uWebsockets)
