Unable to install Nginx Proxy Manager using Portainer on Synology

Question

I followed this guide to install Nginx Proxy Manager (NPM). When I try to create a stack, I get this error:

failed to deploy a stack: npm-db Pulling npm-app Pulling npm-app Error npm-db Error Error response from daemon: Get "https://registry-1.docker.io/v2/": net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

I understand that the solution might be in this post but how can I fix it in my case?
