"403 Forbidden" on any *.txt and *.md Files

Nextcloud version : 19.0.4 (lasted in stable channel)
Operating system and version : Debian 9.13‬ with Plesk Obsidian 18.0.31
Apache or nginx version : Apache/2.4.25 (Debian)
PHP version : 7.4.12

[My english isnt the best but i try my best to describe my problem as best i can] :sweat_smile:

The issue i have, is that all my Files with the extension *.txt and *.md
getting errors at the sync

Server give “403 Forbidden” from “PUT https://…/[Filename.md “or” Filename.txt]” as answer (skipped due to earlier error, try again in XX minutes)

Screenshot 1: (.md - File)
image
Screenshot 2: (
.txt - File)
image

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Just put an .txt or .md File in an sync Folder.

Have anyone an Idea in which direction i can search for?

Otherwise, the Nextcloud actually works quite well (except for the fact that the full text search in connection with Elasticsearch and tesseract does not yet work)
