Here's when the error started happening. I'm currently in Italy, not sure what timezone this represents? I think the local server time

This is a problem with steam or your local computer. This is not something we can really "fix" on our end.

If your game does not authenticate with steam, our servers cannot let you play on our servers. Cheaters will frequently prevent authentication with steam in order to join our servers when they are currently banned.

I'm having this issue--Help!

1. Is Steam Down?
   Check https://steamstat.us and make sure that Valve's servers are online.
2. Go Offline & Back Online:
   In your steam app, select Steam -> Go Offline and then Steam -> Go Online to refresh your steam session.
3. Restart Steam (or your computer!)
   In task manager, end the "Steam" task and re-launch steam to reboot the service.

If this issue persists for more than a day, please open a new ticket. Thanks!
