TYPO3 Core

Suppose we have a website address https://www.example.com

To reproduce:

• have a Site Configuration with a language set with
  

  base: 'https://www.example.es/'
  

• translate a page with title "test-default" with that language
• change the title of the translated page "test-es"

Result:
a new sys_redirect record is created with source_host www.example.com instead of www.example.es.
So when an user browses the default language of this translated page:

https://www.example.com/test-default

is redirected to:

https://www.example.com/test-es

that doesn't exist and throws a 404.

Correct redirect link should be:

https://www.example.es/test-es
