Hi @Roberto Nunez ,

According to the current information, I can't judge the specific cause of the problem, and I need your assistance to provide more information so that we can solve this problem together:

How did you create your workflow? What are the specific steps?

What is the function that needs to be done?

Try these to see if error clears:

1. ​Ensure the application pool is started.
2. Confirm port 443 and port 80 are open for incoming and outgoing traffic on your firewall
3. Restart IIS
4. Restart the server

And there is an article for your reference:
