Some Jira and Confluence instances are currently not available. Atlas CRM relies on Jira and/or Confluence to give you access to the platform. When your Jira/Confluence is not available, you will also not have access to Atlas CRM.
You can follow Atlassian's Statuspage Incident here: https://status.atlassian.com/incidents/2x4splh4hgvq
. As soon as Jira and Confluence are available again, you will have access to Atlas CRM again.
