Artifactory webhook gives "Sending a dummy Webhook failed"

So I have a self hosted Artifactory repository which I wanted to use with a Jenkins pipeline, I deployed Jenkins with ngrok in order to have a fake domain.
When I created the webhook inside Artifactory I used the following URL: https:///generic-webhook-trigger/invoke?token=123**
I tried testing it inside Artifactory and keep getting the error alert "Sending a dummy Webhook failed" and of course, the pipeline not getting triggered
This is the output inside ngrok command, looks like the webhook is getting triggered but ngrok is showing a 404 error
I've been stuck for days and I hope someone here can help me with this.
It seems that the problem is in the webhook service configuration, either in Jenkins or in ngork.
Did you try calling the webhook service directly from curl or postman?
Did you try calling the Jenkins webhook service directly to make sure it is configured correctly?
You may try configuring Artifactory to call Jenkins directly by setting urlStrictPolicy to false in system.yaml.
You can read more about configuring Artifactory webhook in the following article:

Using GitLab Webhooks with Jenkins locally

I keep running into the same error with my setup. I want to configure jenkins and gitlab to automatically build some code on push events. I´m running the docker version of gitlab, while jenkins is running on localhost.
I tried setting up GitLab Jenkins Integration according to the documentation but the connection is continuously refused and I am asked to check my jenkins details(which are 100% correct, since Im using the standard configuration.)
When I tried setting up the webhook manually I´m confronted with a 422 error:
Picture of the response body
I think that this problem might be connected to the fact that I´m trying to set up everything locally. Any help would be appreciated.

Jenkins says: Error: connect ECONNREFUSED 127.0.0.1:80 while trying to list jenkins jobs on slack using hubot

I wanted to have a bot integrated with slack, using which my team can run Jenkins builds. I tried doing it using hubot, following the steps here: https://slack.dev/hubot-slack/
I mentioned all the variables (jenkins_url, jenkins auth -username:password, slack token) in .bashrc and sourced it. The bot connected to slack and when run #hunot help, it will list all the options. So far so good.
I also included jenkins.coffee script in hubot-scripts.json, to reach jenkins however, I'm unable to connect to jenkins. When I run #hubot help, it lists jenkins commands as well. The problem arises when I actually run one of those jenkins commands. When I run #hubot jenkins list, it returns Jenkins says: Error: connect ECONNREFUSED 127.0.0.1:80
I'm not sure what the issue is. On my jenkins host, I'm using nginx, reverse proxy (so that I don't have to use 8080 in url while accessing jenkins). Is there something obvious I'm missing?
Also, how can I access jenkins without user and password?

How can I verify that I can connect to BitBucket before starting a pipeline?

From time to time my pipeline fails due to an HTTP request error 401, while trying to get the jenkins file from BitBucket. In this case, instead of crashing with an error message, I'd like to print a friendly error message and possibly send an email.
Is there a way to check for connectivity to the BitBucket server, before trying to run the pipeline? If this is not possible, can I catch this error somehow, and take action on it?
I'm guessing this would have to be something built into Jenkins, or on the Jenkins server, since my jenkins file resides within the repository on the BitBucket server.
An thoughts would be greatly appreciated, as I'm a Jenkins novice.
