Not staying logged in and forcing offline mode

Not sure if I'm in the right place for this, but as of today my launcher has had lots of issues with launching and logging in. At first I could not even log in with my account, so I thought my account was jacked. Went onto minecraft.net tried to log in, got an invalid access token then got logged out. Changed my password and tried to log in on minecraft.net and still couldn't. However i tried logging into the launcher, and it worked. Everything seemed fine, I could load singleplayer worlds and my skin would show, which usually tells me I'm logged in and have an internet connection. However if i try join any multiplayer servers it says Invalid session please restart.

Upon restarting my account is logged out and it prompts me to login again, even though it is set to keep me logged in. And when i do login again the same cycle continues.

If anyone has a suggestion for a fix, I'd appreciate it.
