Describe the problem/error/question

Connection lost on self hosted n8n. I keep getting this issue :
url/rest/push?pushRef=txrzy1d5i1 500 (Internal Server Error)

The latest version that works with no disconnections is 1.86.1

What is the error message (if any)?

Connection lost

Hi, since I see you’re using Nginx, could you try to change this SSE value to WebSocket and then change to n8n latest version

-e N8N_PUSH_BACKEND=sse \

In my case I have updated to 1.92.2 and with my docker configuration is faling:
services:
n8n:
image: docker.n8n.io/n8nio/n8n

restart: unless-stopped
ports:

“127.0.0.1:5678:5678” # Solo accesible localmente en WSL

GENERIC_TIMEZONE=Europe/Madrid,
N8N_RUNNERS_ENABLED=true,
N8N_PUSH_BACKEND=sse,
N8N_ENFORCE_SETTINGS_FILE_PERMISSIONS=true,
,

volumes:

./n8n_data:/home/node/.n8n # Mapea la carpeta local “data” a la ruta del contenedor
./n8n_export:/home/node/workflows_export,
proxy:
image: jc21/nginx-proxy-manager
container_name: proxy
restart: unless-stopped
ports:
“80:80”
“443:443”,
