## Quick Fixes

This is a page with small problems, to which I have found easy solutions, so as to not litter the blog page.

- Problem: Nextcloud File not supported Error (`exif_read_data(): File not supported at /var/www/html/lib/private/Metadata/Provider/ExifProvider.php#59`).
  Solution: Upload over IP and port rather than over nginx.
  Explanation: Nginx 413 Error - Request entity too large
- Problem: `Connected without internet` on Android after setting PiHole as DNS Server.
  Solution: Make sure you forward both TCP and UDP of Port 53 from your Docker Container.
- Problem: ThinkPad R61 (or any older ThinkPad model, I believe) repeated beep at startup.
  Solution: Check keyboard connector / swap out keyboard.
  Explanation: No keyboard detected on bootup.
