Creating new jira cloud connector Create URL Something went wrong

Hi JamMan0100,

you can try the following steps to try to resolve your issue:

1. Review Permissions:
   Confirm that you possess the necessary permissions to add a connector. This involves being the administrator for both: your organization's Microsoft 365 tenant and your Jira site.
   
   

2. Authentication Details:
   Ensure correct authentication details. If using Basic Authentication, verify that the provided username (usually email ID) and API token are accurate.
   OAuth 2.0 is the recommended authentication method.
   
   

3. Seek Support:
   If the above steps don't resolve the problem, consider reaching out to Microsoft or Atlassian support for further assistance.
