Hi folks! I’m trying to run n8n on a self-managed VPS using Docker with CyberPanel (OpenLiteSpeed) as the web server. Since recent n8n versions require a secure WebSocket (WSS) connection for push updates, I’m trying to get that working behind CyberPanel. Unfortunately, OpenLiteSpeed does not support wss:// proxying natively (only ws://), and all my attempts at getting this to work — or fall back to polling — fail due to cookie/session/authentication issues. I’m open to any working solution — whether that’s using OpenLiteSpeed directly or putting something like Traefik/Caddy/Nginx in front of n8n — as long as: login works reliably session cookies arrive n8n frontend works with either polling or WSS What is the error message (if any)? If using websocket backend (N8N_PUSH_BACKEND=websocket), browser shows: Firefox can’t establish a connection to the server at wss://n8n.sceneryworkshop.nl/rest/push?pushRef=xyz NS_ERROR_WEBSOCKET_CONNECTION_REFUSED If using polling backend, browser shows: 401 Unauthorized on /rest/login and /rest/push Set-Cookie rejected by browser due to invalid or missing domain No active session; login does not persist Please share your workflow This issue happens before any workflow is run — it occurs at the login stage, so no canvas or nodes are loaded. Share the output returned by the last node N/A — login itself fails due to session problems. No node ever runs. Information on your n8n setup n8n version: 1.90.2 (latest at time of writing) Database: Default (SQLite) n8n EXECUTIONS_PROCESS setting: own (standalone container), also tried queue mode Running n8n via: Docker Operating system: Ubuntu 22.04 on self-managed VPS Docker version: 28.0.4 Docker Compose version: v2.33.1 Reverse proxy environment Main web server: CyberPanel with OpenLiteSpeed 1.7.19 SSL: Managed via CyberPanel (Let’s Encrypt) WAF / ModSecurity: Disabled Domain: n8n.sceneryworkshop.nl What I’ve tried External App + Context in OLS configured to proxy / to 127.0.0.1:5678 Added required proxy headers like: RequestHeader set Host %{HTTP_HOST}e RequestHeader set X-Real-IP %{REMOTE_ADDR}e RequestHeader set X-Forwarded-For %{REMOTE_ADDR}e RequestHeader set X-Forwarded-Proto https RequestHeader set Cookie %{HTTP_COOKIE}e Attempted to allow Set-Cookie in response via both: Header set Set-Cookie %{HTTP:SET_COOKIE}e addResponseHeader in the vHost rewrite rules Verified that n8n is fully running and accessible directly via curl: curl -v http://localhost:5678/rest/push > Returns 401 (expected without session) Browser dev tools confirm: No Set-Cookie header received at login Cookie rejected for invalid domain Tried to run Traefik in Docker as a sidecar (on ports 8880/8843), but ran into port conflicts or no change in outcome n8n still works in itself — but login/sessions/push break down behind OLS What I’m looking for A working n8n + WSS setup behind CyberPanel / OLS Or a supported/predictable fallback using polling that works with session cookies Either using OpenLiteSpeed directly or adding a reverse proxy like Nginx/Caddy/Traefik in front — I’m open to any solution that “just works” Thanks a lot in advance — and happy to provide logs, screenshots, config snippets, or docker-compose files as needed! — Hielke

I have a very similar issue. I had to downgrade to version 1.86.1. I was originally running something prior to 1.86.1, then upgraded to 1.91.2 and noticed the same issues with web sockets. I downgraded in steps (skipped 1.87.0) down to 1.86.1 and then everything started working again. My setup is different. I am running n8n in docker, then nginx running locally in the system. The whole setup is in a local LAN, so my domain is something like “n8n.myhost.foo”.

I deploy n8n on openlitespeed with queue mode just using SSE not Websocket and it works perfectly just setup N8N env > N8N_PUSH_BACKEND=sse Another step i produce: Setup proxy on /usr/local/lsws/conf/httpd_config.conf extprocessor n8n-main { type proxy address YOURIPADDRESS:5678 maxConns 100 pcKeepAliveTimeout 60 initTimeout 60 retryTimeout 0 respBuffer 0 } Rewrite rules on your domain RewriteCond %{HTTPS} !=on RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301] REWRITERULE ^(.*)$ http://n8n-main/$1 [P]
