One of 2021’s superior Genshin impact clones, the “Tower of Fantasy,” recently encountered a login failure. Most Tower of Fantasy players claimed that when they tried to log in with their credentials, the system denied them access and displayed the “login failed” caption. Although the game was nominated for the best mobile game, that nomination was incorrect.
Further, Hotta Studio acknowledged this error with this login failed message. As of now, there is yet to be a satisfactory solution to this problem. Being a subsidiary of Perfect World, I agree that developers cannot ignore this issue. It may take some more time to fix it. On the other hand, the error occurred due to your mistake. So, let’s discuss and try to fix it.

Fix: The Tower of Fantasy Login Failed Error
There are two possible ways to fix the failed login error. One side is from the developer, and the other is from you. Listen, if a developer makes a mistake, they will automatically roll out a new update to fix the problem. The developer is still searching for the cause of the login failure error. But do not worry, as per our study, we found some mistakes players usually make that result in such errors. Let’s examine those mistakes and fix them so we can get back into the game.
Fix 1: Restart Your Internet Connection
Whether you use Wi-Fi or cellular, it would be best to restart your internet connection. The login failed error sometimes occurs due to slow internet or when the game’s server is inaccessible to the player. Meanwhile, turn off your data connection and reconnect to get connectivity back. After doing so, try logging into the game, and hopefully, the problem will be resolved.
Fix 2: Restart the game
As a new MMORPG game, when you play the game for a non-stop session, it stores a lot of data on your device. As a result, such data creates an obstacle for the game to run normally. Similarly, when you try to log in again, you see login failed errors on your screen. For such concerns, you must completely restart the game on your device and try again to play it.
