This error is appearing in the logs, I only modified the identification information in this log. There are several lines with different IPs.

2025/10/10 13:38:26 [error] 2439194#2439194: *5035166 recv() failed (104: Connection reset by peer) while proxying upgraded connection, client: ip_client, server: api.domain.com.br, request: "GET /natsws HTTP/1.1", upstream: "http://127.0.0.1:9235/natsws", host: "api.domain.com.br:443" ........

My nginx is like this in natsws:

location ~ ^/natsws {
    proxy_pass http://127.0.0.1:9235;
    proxy_http_version 1.1;

    proxy_set_header Host $host;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header X-Forwarded-Host $host:$server_port;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
}

What solution should I take or processes to follow?
