This is an account issue. We do not have the tools to help you on this tracker.
Please contact Minecraft's Customer Support, they should be able to whitelist your IP.
I work for a company that teaches Java using Minecraft. We are located at 128 colleges in the US. We've purchased a full account (Minecraft.edu denied us) for each machine.
At our large locations where 50-100 students are logging in at one time (each with separate accounts/passwords), we're noticing that after the first 30-or-so log in, the rest are getting error messages that read: "Error! Unknown e-mail address or password." If we tether to a phone or try from our office, the account/password works fine. So it's something to do with the IP address, we think.
Accounts are being denied after a certain number of logins; but the next day they'll work.
Unfortunately, we can't split computers over multiple IPs as we're on college campuses and they're stingy.

Got a notice that you were sent from Customer Support -> Tech Support -> Here. Leaving this ticket open until confirmation / further clarification.
I appreciate it Kumasasa. We know there's a lot of people out there doing things the wrong way...we bought hundreds & hundreds of accounts to keep it legit. Trying to figure out the best place to get it fixed and/or advised of another method.
Is there a Whitelist for IP Addresses that we could be added to? Is that a feature of the PC version?
We've a problem like this since a few weeks. We have two accounts on the same IP adress, which both don't work anymore. Our neighbour can't login or make a new account on our ip-adress. All accounts work fine on other IP adresses. We get the same errors.
We found out that our IP-adress was on the blacklist since december. This morning we scraped it and now it is still not working.

This is a technical issue and something that customer support would probably not be much help with. What a poor response to a real problem.
This actually falls under Account Support. Throttling happens when multiple users fail to enter the correct password, and with 50-100 people, this can be the case fairly easy. Any whitelisting can only be done via account support, and alternatively, there is the Education Edition.
It's not a problem, the system works as intended to prevent attacks on user information.
This is not a bug of the game, but most probably a security measure at the login servers.
