Can't Login to Icloud or Apple Store after vacation

I was on vacation in another time zone. During that time there was a time change (spring forward.) I had no problem logging into my itunes account on vacation. Since I've been back, I get a Verification Failed when logging into Apple ID or Icloud. (Both work on my phone and I was able to log in online, as well.) All advice was to change time. When I turn on 'set automatically' it just goes around and around. When I fix it manually, I still cannot log into the accounts. Again, I can log into the accounts on other devices and I had no issues until I arrived back into my time zone. Please help. I cannot afford to lose all of the apps on my phone by doing a hard reset. (I did a soft. Didn't work.) Also, the software is updated.
