@atrilahiji said in Cannot reach backend server: So this appears to be an issue on Firefox rn that has been reported on their forum. https://community.n8n.io/t/connection-lost/1471/49 Using a chromium based browser seems to be fine in my testing. Edit: This post seems to have a suggested solution via the NGINX config https://github.com/n8n-io/n8n/issues/36#issuecomment-539647882 @nebulon @girish The mentioned fix is already active. See https://git.cloudron.io/cloudron/n8n-app/-/blob/master/pkg/nginx.conf#L64 But the issue persists.
