621 bug getting econnreset error on production server

[JoelWiebe]

Added basic error handling for web socket server and frontend client.

Details

• As source of error is unknown, provided generic handling to catch thrown errors (did not implement showing errors to the user"
• Basic support for dropped wifi appears to already be supported, if you toggle off the wifi in your browser (offline throttling in browser dev tools) then back on over a short duration, the web sockets should continue their connection

Test

• No new client or server-side errors
• Handles short duration loss of wifi

Closes #621
