Description
Hi All,
When I use a subdomain for jupyter notebook, though I can view the content, but when I want to edit or create new file I will get a error.

When I use ip all things is OK.

Research direction
The issue names no source files, tests, or entry points. Reproduce file creation and editing through the custom subdomain and compare it with access by IP, then inspect the error shown in the linked screenshot; done means both operations work through the subdomain.
