Slack Trigger fails to fetch the event

Questions
1

I was setting up a slack bot application to perform some tasks, but today the trigger event on bot mention stopped working. I use the right credentials as I can send a message from this bot, but webhook url which was working before just started failing to fetch the event. I thought that I could just use another trigger node and put its url in my slack application settings, but I faced this error:

Maybe you know what might have been the reason of such unexpected fail?

Hi there, it’s one of the way of slack to test your webhook to make sure that it’s active and ready to receive data from slack

but usually, n8n handle this automatically

if you are pasting the production url, make sure that the workflow is active so it will listen to it

so, activate the workflow and do the copy and pasting of the url all over again to trigger the challenge
