If you want to connect your Jira account to Marker.io in order to report issues, you will need to know which kind of Jira product your team is using.
Jira either comes as a cloud service or a self-hosted platform. To find out which you are using, simply head to Jira and look at the URL.
If it contains
atlassian.net, it means you are on the Cloud version.
If it doesn't contain
atlassian.net, you are on a Self-managed instance.
