Hi, can you confirm that locally on the server you can reach the n8n on port 5678 and provides the webinterface

Hi, so what did you configure in IIS? The error indicates a name resolution problem.

I made a reverse proxy to my port made an inbound rule on my domain to redirect my selected port on which n8n is running i guess the problem is in my config file.

Hi, yes most likely but without seeing a configuration it’s hard to say anything really

Hi, you have a tunnel as well as a reverse proxy?

There is no webhook_url

Also the most important is your reverse proxy configuration and whether the proxy is publicly reachable or you need tunneling
