Describe the problem/error/question
I am running N8N locally on Docker and use Ngrok to enable the instance to connect to Slack.
In my workflow, I am using Slack trigger (New message posted to channel) → if node to filter out the subtype of the slack message → Slack get user’s profile node.
I was using this workflow for several days and it was working fine up until today it decides to throw me this error at the Slack get user’s profile node
I have tried to: update Docker, update Ngrok file; create new credential using OAuth2 API (when I try to create this new credential, it gave me below error)
What is the error message (if any)?
Problem in node ‘Get a user’s profile‘
The service refused the connection - perhaps it is offline
