I stumbled upon this issue when mixed content http(s) errors occurred in editor screens.
No need to re-open this issue.
For reference when people find this again to help them solve their problem.Thank you maintainers for having this module in Drupal 8+
These issues are merely configuration.In example not setting the domain source or allowing it to be accessible from other domains.
There is even a config option to fix these AJAX errors when behind proxy or localhost
You find it under /admin/config/domain/domain_source
