ICloud Server error will not let me sign out

Question

(this is on an iPhone 6)
So Recently I created a new Apple ID because I'd forgotten my security questions. For about three months, I still had that ID signed in on my iCloud, which wasn't a big deal for me as I rarely back up via iCloud. However, whenever it prompted me to sign in, I'd put in the password, which was for sure correct as I changed it twice, it would continually pop and prompt me again. So I put in the password, again.
I Decided I should probably research this problem a bit further, so I went into settings>iCloud. Naturally, I click where my name is displayed. It asks me to sign in. when I do, it kind of glitches by having a window pop up prompting for my password(mind you while its verifying), then for A quick moment you see a check mark next to the password, then the page closes itself, taking you back to the majn iCloud screen. I then get a popup that says "A server error has occurred"
Any Ideas? It would be greatly appreciated! If you need pictures I'd be glad to put them up

If your device is signed into an old ID ("email address") that is an earlier version of the ID you want to sign in with, do the following:
If you are using iMessage and FaceTime, make sure you are signed into these services with your current ID.  If they are signed into the old ID, go to Settings>Messages>Send & Receive and Settings>FaceTime, tap the ID, sign out, then sign back in with your current ID.
Then temporarily recreate the old ID by going to https://appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID.  Click edit next to the primary email account, change it back to your old email address and save the change.  (You should not have to verify the old email account so it doesn’t matter if you no longer have access to it.)  Now go to Settings>iCloud, turn off Find My iDevice and enter your current password when prompted (even though it prompts you for the password for your old ID).  Then save any photo stream photos that you wish to keep to your camera roll (unless you are using iCloud Photo Library).  When finished go to Settings>iCloud, tap Sign Out (or Delete Account if you are not running iOS 8) and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud).  Next, go back to https://appleid.apple.com and change your primary email address back to the way it was.  Now you can go to Settings>iCloud and sign back in with your current iCloud ID and password (your data will download back to your device).
