(obviously I only replaced my domain here, it is correct on my server)

Describe the problem/error/question

“Connection lost” appears at the top of my workflows. I am unable to use certain tools such as Discord webhook integration. Attached is my docker compose file and apache config.

What is the error message (if any)?

“Connection lost”

Hi @HoggyTheWizard ,

is it a local installation or on a cloud server?
Because this looks like a local machine:
ports: - “127.0.0.1:5678:5678”
