I’ve carefully implemented the change, but for some reason I’m still getting a “404 page not found” from Pangolin after restarting the VPS. It seems that it all comes down to that one line in my previous comment (`filename: /etc/traefik/dynamic_config.yml`), if I leave it present then Pangolin works, but if I comment it out or replace it with the two lines from your comment (the directory and the watch lines), then Pangolin gives me a 404. And I have already copied the dynamic\_config.yml file into the `/root/config/traefik/rules` dir. What could I be missing? ---

Thanks for this. Took a bit to install correctly because there seem to be some differences from the initial post and what’s in the comments, but so far I think I have it working ok. In terms of the templates, should we use what is posted on GitHub or here? And how do we confirm that they are in use besides saying “Protected” in the webui? For example, with rate limiting and security headers. ---

yes if it’s related to technical issue or feature update where we have to look into code then GitHub is the best place. any setup help, you can raise here or on our cord where you feel comfortable. ---

Ok Looks like middleware manager has started correctly. Assuming pangolin in working create a new site (must be local) and create a resource and point it at localhost:3456 . Give it a subdomain name. Then try to access the middleware manager on that subdomain ---
