ResponseError: Invalid origin! after upgrade to 1.88 - Conneciton Lost

Questions

Hey there,

I get an “ResponseError: Invalid origin!” after upgrading to 1.88 it was working fine with the previous version (I think it was 1.86). In the UI I get the “Connection lost notificaiton”

I’m using self hosted version and docker compose to run it with traefik

ResponseError: Invalid origin!

      - local_files:/files

I’ve tried different solutions but none of them works (like setting VUE_APP_URL_BASE_API, N8N_PUSH_BACKEND, etc)

Any help is appreciated. Thanks

Up for this, got same problem… already tried to create custom rule for Origin to hostname on cloudflare but not fix anything

I figured out the issue, in my case the docker was running with a proxy from apache so I had to add this to the apache config:

ProxyPreserveHost On
RequestHeader set Origin “https://n8n… domain”
RequestHeader set X-Forwarded-Proto https

hey thanks for your insight, its fixed my n8n on swarm cluster. just config nginx by adding this:
proxy_set_header Host $host;
proxy_set_header Origin $http_origin;

For my other Openlitespeed webserver solved from this solution by config on cloudflare

This solved the problem for me using nginx as reverse proxy

location / {
        proxy_pass http://localhost:5678/;
        proxy_http_version 1.1;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Host $host;
        proxy_set_header Origin $http_origin;
    }
