What is TERA Online?

TERA Online is an MMORPG released quite a while ago (2011 was its initial release in South Korea). It had a bunch of closed and open beta testing sessions before the official release.

The game has regularMMORPGfeatures such as PVP, crafting, and questing, and uses a non-target battle system. This means that instead of clicking the target and selecting things to hit them with, you just fire away as you would in an action game.

More so, you’ll need to be quite skillful, considering that you’ll have to dodge enemy attacks actively. That’s TERA Online in a nutshell, although we skipped a lot of awesome features.

We’re not here to talk about TERA, but we can (hopefully) help you fix the user authenticationerrorin the next few following sections.

How to fix TERA restricted account sign in error?

1. Try using a VPN

The usability of aVPNin such issues has been widely debated. The general consensus is that more often than not aVPNwill do the trick, as it does with many other connectivity issues.

Private Internet Access is a Kape Technologies product and also one of the fewVPNsthat offer 24/7 live chat support.

Note that if theVPNfix doesn’t work, you shouldn’t give up just yet. Disconnect from the server you chose, connect to another (preferably fast) one and try again.

Private Internet Access

Network congestion is usually a quite decisive factor that determines the occurrence of connectivity issues. Thus, if theVPN server is overcrowded, you may want to try another one.

2. Try logging in with Facebook

Reportedly, users noticed that logging into their TERA Online account through Facebook seemed to work. Just use the game launcher and instead of logging into your TERA Online account, use your Facebook account to perform the operation.

However, for this fix to work, you’ll need your TERA and Facebook accounts to be linked. This can be easily achieved on the Account Settings page on the TERA Online website.

Long story short: make sure your Facebook and TERA accounts are linked, then try to log into TERA with your Facebook account.

3. Avoid logging from multiple accounts

Apparently, TERA Online has this 24-hour block that applies to users who trylogging infrom several accounts on the same machine, in a short interval of time.

To prevent that from happening, only stick to one or two accounts. As far as we know, there’s no limit tolog-inattempts from the same account, as long as you don’t switchIP addressesfrantically between attempts.

Also, it would be a great idea to check if you were banned. Many users mistakenly believed thiserrorhad something to do with their bad connection when in fact, their accounts were in fact inaccessible due to bans.

Final thoughts on fixing TERA user authentication error

All in all, if you’re trying tolog intoTERA Online and receive the user authenticationerror, don’t panic. There are a few reasons why this could be happening, and a bunch of fixes for these reasons.

First and foremost, you should make sure that your account is not banned. Else, trying any of the fixes might be completely useless.

One of the most popular fixes for this issue is using aVPN. If using aVPNseems to be in vain, try switching servers between ditching this suggestion. It could save you a lot of time and hassle.

Last, but not least, you could trylogging inwith your Facebook account, as suggested by various users on the TERA Online forums.
