First things first: I'm French and beginner, so please bear with me if I don't get what you guys say at first, especially when you will get technical I'll do my best anyway.
Soooo...where to begin...: I can't access my Owncloud on my Raspberry Pi for many weeks now using the online interface. When I looked into it more closely, I found out that the IP used to set it up at first wasn't the same. Doesn't work either with the new IP, can't add that new IP into the Android app, nada. I added this new IP into config.php, zero result.
So here I am, at a complete loss! I don't know how to get to my files, and I can't find a solution anywhere online.
I believe that my description is incomplete, please let me know if you have questions.
