Thank you for using Teachme Biz.
We are pleased to inform you that the domain migration for Teachme Biz has been successfully completed.

Overview

  • We have successfully changed "*.cloudfront.net" to "*.teachme.jp" to enhance your access security to Teachme Biz.
  • If you experience issues such as Teachme Biz not displaying correctly, please check that the communication permission settings for "*.teachme.jp" are correctly configured.
  • If you do not know the communication permission settings, please contact your company's information system department.

Purpose

If you have set communication permissions on your network, you needed to allow "*.cloudfront.net".
However, we recognize that "*.cloudfront.net" has a wide range of permission, and there may be cases where you may have concerns.

To address this, we have now successfully changed ".cloudfront.net" to ".teachme.jp", allowing for more secure and focused communication permission settings.

Details of Change

The domains that must be allowed have been updated as follows:

Domains Before After
teachme.jp
*.teachme.jp
*.cloudfront.net
teachme-official-video-tokyo.s3.ap-northeast-1.amazonaws.com
teachme-official-report-csv-tokyo.s3.ap-northeast-1.amazonaws.com
