Minecraft won't allow me to login (launcher and website)

Whenever I try to login to Minecraft Launcher Java Version, it will always say: Sorry! Make sure you are online and try again. This issue has persisted for 1 week now and I am struggling to find a solution. Also, whenever I try to log in to the Minecraft site, the Log in button goes nowhere. I click on it, and it turns grey but it never does anything. Logging in to minecraft on the website using MY PHONE works, but its useless there. Is there anything I can do to fix this issue? I am desperate for an answer!
