other thing, i start this on aws vps, but the server was calling the privete IP note the public ip, how can i fix it?

[canove]

About the first error, it may be related to whatsapp authentication. Some features in system try to use "wbot", and if its still in "authenticating" mode (before read QRcode), it throw an error. I will try to solve this in a few days.

About running it in a VPS, you need to build frontend app (in frontend folder, run: npm run build). It will create a folder called "build", that you can publish with apache or nginx.
You should also change cors setting in backend\src\app.js to improve security.

Note: Its not tested it in a production environment, and I'm not sure that its safe to use.

I did it, change the ip's 'localhost' to 'ipv4 of vps' but still have error,
Failed to load resource: net::ERR_CONNECTION_REFUSED localhost:8080/auth/login:1

i already change the ip's, but still connection was localhost, and i'm trying fix it tks

[marlon33]

I solvedd this problem, the host did not connect to the server, because my vps ipv4 is private, so, i used a no-ip to connect host > server
