Error 500 at login with vuejs

Hello, online I can login normally, instead locally I get erorr 500 trying to do the login, why?

On both sides I have the same configuration:
fabricjs => version:“2.3.6”
vue => version:“2.6.10”
Bootstrap => version:“4.0.0”
php 7.3
node --version => latest stable
npm --version => latest stable

500 means that something unexpected happened on the server (for example that it crashed). Check the error on the server, and you’ll get a clue to what the client did wrong.

What differs on the client when it runs locally is (spontaneous list):

  • Possible protocol (HTTP VS HTTPS)
  • Domain (which might give you problem with the same-origin policy)
