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

Pacman install fails with 404 (`error: failed retrieving file 'X' from Y : The requested URL returned error: 404`).

Replace `/etc/pacman.d/mirrorlist` with a new file generated at https://archlinux.org/mirrorlist/.
Then run `sudo pacman -Syyu` to update with the new mirrorlist. Make sure to use 2 y's, to force the new changes.

Your mirrorlist is outdated, possibly due to the recent pacman git migration.

HomeAssistant not connecting over reverse proxy | Make sure you have enabled Websockets Support or similar functionality in your reverse proxy client. | HomeAssistant uses websockets for its frontend.
