Reasons For The Minecraft Invalid Session Error

You sit down to play your favorite game, Minecraft, only to find the dreaded “Minecraft invalid session error” message staring back at you. There are a few reasons why this issue might pop up when trying to play Minecraft.

One reason for the Minecraft invalid session error is having an outdated game client. Newer versions of the game get released with bug fixes and improvements that help prevent issues like this one from happening. If you’re using an older version of the game, some feature or another player’s actions may cause conflicts, leading to this annoying error message.

Another potential culprit behind the Minecraft invalid session error is corrupted game files. This can happen if something goes wrong during the installation or update process, leaving important pieces of data damaged or missing entirely. When these essential files aren’t working properly, they can cause all sorts of problems – including our pesky invalid session error.

Invalid login credentials may also be responsible for causing the Minecraft invalid session error. Sometimes, we accidentally mistype our username or password when logging into our account; other times, our accounts may become compromised by hackers who change our passwords without us knowing.

Regardless of how it happens, not being able to authenticate your account correctly will result in this error message.

Now that we’ve covered some common causes behind the Minecraft invalid session error, let’s dive right into fixing it so you can enjoy your blocky adventures! The first solution involves simply logging out and then logging back in…

Solution 1: Logging Out And Logging Back In

One of the easiest ways to fix the Minecraft invalid session error is by logging out of your account and logging back in. Sometimes, this issue happens when there’s a problem with your login details or if you’ve been playing too long without restarting the game. Here’s how to log out and log back in:

  • First, close your Minecraft game completely.
  • Next, open up Minecraft Launcher on your computer.
  • Then, click on your username at the top right corner of the screen.
  • Finally, choose “Log Out” from the drop-down menu.

Now that you’re logged out, it’s time to log back into your account:

  • Open up the Minecraft Launcher again if it isn’t already running.
  • Enter your email address (or username) and password in their respective fields.
  • Click on “Log In” to sign in to your account.
  • Wait a few moments as the launcher downloads any necessary updates or files.

Once you’re logged back into your account, try relaunching Minecraft and see if the invalid session error has been resolved.

Remember that sometimes even simple things like turning off and turning on our computers can help solve problems like these. So before trying anything else, give it a shot. You might be surprised at how often this easy solution works.

But what if this doesn’t work? We have another solution for you coming up – deleting some game files may do the trick! Let’s move on to our next method, ‘ Solution 2: Deleting Game Files.’

Solution 2: Deleting Game Files

If the first solution didn’t work for you, don’t worry! There’s another way to fix the invalid session Minecraft launcher error. This time, we’re going to try deleting some game files. Sometimes, these files get messed up and cause problems with your game. Don’t be scared – it’s easy to do!

First, make sure that you close down any open instances of Minecraft or its launcher. Next, find the folder where all your Minecraft stuff is stored on your computer.

On Windows computers, this is usually in a place called “AppData.” To get there quickly, press the Windows key + R at the same time; then type “%appdata%” (without quotes) into the box that pops up and hit Enter.

Now that you’ve found your Minecraft folder look inside for a subfolder named “.minecraft.” Inside this folder, search for two more folders: one named “versions” and another named “launcher_profiles.json.”

Go ahead and delete both of those folders! But before doing so, if you have any important saves or customizations backed up elsewhere because deleting these files will reset them.

With those problem-causing files gone, reopen the Minecraft launcher and let it redownload everything fresh. Once it finishes downloading all the necessary files again, give your game another try – chances are high that this invalid session Minecraft launcher fix has done the trick!

Solution 3: Updating Game Client

As the saying goes, “out with the old, in with the new,” and it’s time to look at another solution for fixing the Minecraft invalid session error. Sometimes outdated game clients can cause issues that result in errors like these. So let’s get into how you can update your Minecraft client.

First, you must find out what Minecraft version you’re currently using. To do this, open up your game and peek at the screen’s bottom right corner. Some text that tells you exactly which version number you have installed should be there. Jot this down somewhere safe to compare it with the latest available version later.

Next, head to the official Minecraft website (minecraft.net) and click “Get Minecraft.” This will take you to a page where you can select which game edition you are looking for: Java Edition or Bedrock Edition. After selecting the appropriate edition, scroll down until you see an area called “Latest Release” – here’s where our trusty piece of paper comes in handy.

Compare your current version number with the one listed as the Latest Release; if they don’t match up, it’s high time for an update!

Once you’ve determined that an update is needed, simply follow the instructions provided by Mojang for downloading and installing said update, depending on whether you have Java Edition or Bedrock Edition. And voila! You’ll now be running on a shiny, updated version of Minecraft.

With everything refreshed and renewed in-game, let us move forward towards troubleshooting those lingering invalid session errors within our Minecraft launcher itself–and remember: persistence pays off when tackling technical problems like these.

Head over to Mojang/Microsoft website depending on your account type (Mojang: https://www.mojang.com/ or Microsoft: https://account.microsoft.com/), and sign in using your current credentials. Once logged in, update your password following the instructions provided on-site – remember not only to make sure it’s strong enough but also unique from other passwords used elsewhere online!

After successfully changing our secret code words, we should now be able to relaunch MC as normal without encountering any more error messages.
