Errors with Youtube Tutorial

Last 5 minutes of this video -, I hit the register button and I get these errors:
Uncaught (in promise) Error: Network Error
at createError (webpack-internal:///./node_modules/axios/lib/core/createError.js:16)
at XMLHttpRequest.handleError (webpack-internal:///./node_modules/axios/lib/adapters/xhr.js:87)

Can’t figure out what’s causing them since I’m pretty new and have no idea where I’d look to even fix the issue. What’s weird is I’ve got all the exact same code as the guy in the video. My node server DOES NOT respond when I click the register button. Anyone got any ideas?

A problem with the Authentication service I guess.
