Maybe I'm stupid or I misunderstand the custom list.
I looked to my query lo and saw many Windows/Microsoft querys which are not blocked with my lists. So I blocked them manually ocer the "Block" button.
Now I would like to have them in a list. I copy pasted them, uploaded it to my Gdrive, copied url and updated Gravity. But the it ignores the entries.... why? Why 134 entries? there are only 20 on the list.
The list you've linked (RPiList) is in a valid format.
Yours obviously isn't, as it reportedly contains only stuff like "<" "try{" "/*" "authors" "apache-2.0".
You'd have to make sure that the file is accessible and has valid contents.
Perhaps the https://docs.google.com/... URL that you've obfuscated is not pointing to a publically accessible resource (e.g. because access requires a login)?
Also, you could host private lists on the Pi-hole machine itself, e.g. a file stored at /media/lists/personal-blocklist.txt could be added to your Pi-hole via file:///media/lists/personal-blocklist.txt
But it does not match any of Pi-hole's supported formats.
(EDIT: Above was copied from the source code of the error page your link has produced for me, but you still can find a few of the invalid non-domains that Pi-hole has encountered when trying to import your list from that URL.)
You have to host that as a plain text file, just like the RPiList you've linked.
Google Drive/Docs does not allow for direct hosting of files, as such. They are always wrapped in the web application and are actually HTML. You might be able to copy the link for which your file could be directly downloaded and use that. Try using 'curl' from your pi to see if the URL produces plain text output of your list vs anything else.
Strange. My colleague in the office can access it Anyway xD
Your colleague is accessing the link using a browser.
The browser will receive the page (it's a HTML page, as explained by Bucking-Horn) from Google and will render the content in a way humans can read it. This page contains buttons, icons, links, javascript code, text, ... Your list is just a small part of the full HTML code.
