Recently I was invited to a Realm, but I've been having issues joining. Basically, whenever I try to join the Realm, I get to "Downloading Terrain" for a split second, then it instantly switches to "Connection lost: Disconnected".

I've tried joining other servers to Make sure it isn't just the Realm, on the server list it shows the connection strength and everything, but as soon as I join, I get the same thing. What's funny is I was able to personally host a Minecraft server completely fine from my own IP, and I'm able to play online any other game perfectly fine, but Minecraft is the exception here.

I've already Googled all I could think of, trying multiple methods, but so far nothing has worked. I don't really have any other details to give, the launcher acts perfectly normal, not even throwing up an error in the log.

Basically all I'm asking is how can I fix this? I know I didn't give out much details, but hopefully someone can throw out any ideas?

    Are you using any mods? Have you checked your internet connection for dropped/lost packets?

  • It sounds like you have a bad internet connection

  • I am not using any mods (I actually thought that was an issue, and even went to the extend of redownloading the 1.9 jar) and my internet is fine. Playing/hosting servers on any other game is pretty much lagless.

    @galacticninja not a dupe. One is instant error, other is timeout.

It sounds to me like you have something blocking Minecraft from your computer. Do you have something like MeetCircle on? This is the same with mine--single player worlds WILL work, but trying to connect to servers will automatically disconnect you.

  • No I don't have anything like that on, unless it's like reeeaaallyy hidden or something. I've already tried disabling what I could, and still no luck, sadly.

I've been having that problem also. Maybe your AES key generator is not available. To make it available, it's sort of dizzy doing all that stuff - so It's best if you contact Mojang for support in an e-mail.
