      Summary

      With MIG-1210 resolved, there are still cases where CMAs error when it cannot reach a particular endpoint described in IP addresses and domains for Atlassian cloud products.

      For customers that use custom java cacerts truststores, CMAs should be more proactive to detect problems and provide better error messages to the customer.

      There are various errors that appear when a CMA cannot access an endpoint.

      Suggestion

      Complete additional network connectivity checks earlier in the migration process and present better error messages when failures occur.

      Workaround

      1. Make sure your Jira or Confluence instance has is allowed to reach the JCMA or CCMA endpoints as described in IP addresses and domains for Atlassian cloud products
      2. If you use custom Java cacerts files, make sure the following domain certificates are trusted:
        1. *.atlassian.com
        2. *.atlassian.net
        3. *.s3.amazonaws.com
        4. *.s3-us-west-2.amazonaws.com
