Cannot Install Addon from the local Atlassian Spring Boot Project

Hi everyone,
I was facing an issue where I cannot have the add-on application to be installed in my Jira instance.
I have created a local project using the ‘atlassian-connect-spring-boot-starter-1.3.1’ and hosted the application
via ‘ngrok’ which provides a https tunnel to my local application. The property descriptor that the application retruns when the /atlassian-connect.json API is called is :
URL ::

  "name": "Spring Boot Lightning Demo",
  "description": "Doesn't do heaps",
  "key": "atlassian-connect-spring-boot-sample-gradle",
  "baseUrl": "",
  "vendor": {
    "name": "Atlassian",
    "url": ""
  "authentication": {
    "type": "jwt"
  "lifecycle": {
    "installed": "/installed",
    "uninstalled": "/uninstalled"
  "apiVersion": 1,
  "scopes": [
    "read", "write"
  "modules": {
  	"webItems": [
        "url": "/show?contentId={}",
        "location": "system.content.action",
        "context": "addon",
        "target": {
          "type": "page"
        "tooltip": {
          "value": "Show as JSON"
        "key": "lightning-to-json",
        "name": {
          "value": "Show as JSON"
           "value":"ATMS WEB"

I installed the application once successfully but now the application throes the JWT token not being verified error and on the manage Addon page of the jira account HTTP 401 is being thrown.
Please Help to resolve this issue.

Hi @sasharma,

Have you tried uninstalling it, deleting the store.db, and installing it once more?
