2fa authentication stopped working

Bug

Body

After months of using Okta with no issue, this method of signing in suddenly quit working about a month ago. I've actually got two accounts (from two machines); one for work and one personal. The same issue has happened on both.

For one account, Authy works but Okta does not (while Okta works just fine everywhere else), and on the other account, neither work.

I've resorted to using SMS verification only after being locked out trying to troubleshoot this. Yes, I've tried re-establishing the 2fa, and yes, I religiously keep the recover code (thankfully; I needed them before getting wise to seeing up SMS)
