For League of Legends players encountering the annoying “Unexpected Login Error” in LoL, here’s the info you need on what’s causing it and how to solve it.
The “Unexpected Login Error” message usually appears as fans are trying to update their League of Legends client, downloading a patch or a hot-fix. Similar login issues can be Windows’ fault on the operating system level, but fixing this one is going to involve some more base solutions and a bit of wireless router maintenance. Here’s the context around what’s almost certainly causing your error, and how to resolve it.
The “Unexpected Login Error” bug is typically caused because of a poor internet connection. Unlike the “An Unexpected Error with Login Session” error that also frustrated players, this one is usually entirely fixable by the player.
The bug is often caused by an issue with the player’s ISP or with the computer itself. But not to worry. Here’s how to solve this issue.
If this doesn’t fix it, it’s likely an issue with the DNS server you’re using. DNS stands for Domain Name System, and is essentially representative of the channel that your router uses to communicate with the internet. Here’s how to swap your DNS server easily via Windows.
If none of these solutions work for you and the PC still experiencing other internet issues, it’s likely the fault of your Internet Service Provider. If neither solution has helped, it’s best to either contact your ISP directly to ask about these connection issues, or if the issues are strictly temporary, to just wait for your internet connection to stabilize again. If it’s still not working after a prolonged period and none of these issues seem to be at fault, you can as a last resort try to contact Riot Games Support directly.
That’s everything fans need to know to fix the LoL bug “Unexpected Login Error,” and hopefully it provides the resolution that you need.
