Please check this video on how it behaives?

Erros:

• Unexpected error: Invalid response: No root multistatus found
• Folder not found

Environment:

• I am using Hetzner deployment of Nextcloud called Storage Share

• It seems to be Nextcloud Hub This Nextcloud is on version 31.0.10

• It happens in the WebDav too

• I was not able to find a similar issue

Steps to reproduce

1. Create a directory name test.php
2. Open it
3. Try to add a file in it

Expected behavior

Directories ending in .php should act like normal directories and the engine should be name agnostic

Could be a provider limitation, in my instance v31.0.12 it works (created folder test.php then uploaded a file test.pdf inside it).

Thank you @solracsf for verifying, could you please share your deployment stack so I can check with Hetzner to find the solution?

With regards.

Nginx + php-fpm, by the books.
Check with Hetzner and report back if needed. 👍
