GET https://localhost:4000/socket.io/?EIO=3&transport=polling&t=NBxR_0e net::ERR_SSL_PROTOCOL_ERROR

[marcoippolito]

I ran my own signal server:

(base) marco@pc01:~/webMatters/vueMatters/GGC/node_modules/@geut/discovery-swarm-webrtc/bin$ ./index.js
discovery-signal-webrtc running on 4000

and in DiscoverySwarmWebRTC.vue file I put:

<script>
    import swarm from '@geut/discovery-swarm-webrtc';
  const sw = swarm({
    bootstrap: ['localhost:4000']
  })

Executing:

(base) marco@pc01:~/webMatters/vueMatters/GGC$ yarn electron:serve

I get this error:

GET https://localhost:4000/socket.io/?EIO=3&transport=polling&t=NBxR_0e net::ERR_SSL_PROTOCOL_ERROR

I'm developing my app on a local PC where I'm running an NGINX webserver.
in the nginx configuration I added:

upstream websocket {
    server ggc.world:4000;
}

server {
    listen 8443 ssl;
    server_name ggc.world;

    ssl_certificate /etc/letsencrypt/live/ggc.world-0002/fullchain.pem; # managed by Certbot

    ssl_trusted_certificate /etc/letsencrypt/live/ggc.world/chain.pem;
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

    location /p2p {
        proxy_pass http://websocket;

        proxy_set_header Connection "Upgrade";
        proxy_set_header Host ggc.world;
    }

We are not longer use socket.io, you are using an old version of discovery-swarm-webrtc
