This has been happening for almost a year now. It didn't really matter back then because I didn't play servers that much, but now that I want to play on servers, this is a real problem.
Whenever I try to join a server, it says:
"Internal Exception: java.lang.Error: java.security.NoSuchAlgorithmException: AES Keygenerator not available".
I am running Minecraft version 1.12.2 on Windows 7 (although it didn't work on the pervious computer, which ran Windows 10), I have moved to another country since buying the account (North America to Korea). I have actually tried this on TWO accounts, both of which was bought in America and had no problem with servers. (One of them was able to play servers in Korea, then stopped working. The other one never worked.)
*The game, server, and client is and always was a non-modded, Vanilla client that was legally bought from Minecraft.net. Nothing, not even a map, was downloaded onto it.*
I actually changed computers since it stopped working, but it won't work on both. I believe it sometimes works, but haven't seen it working for months.
I looked this up and was recommended that I download a new version of java, (latest version and the American version as well) which I did more than I can count, but to no avail.
I have followed all the directions from that post with no luck.
Once, it yielded a different error: "java.lang.NullPointerException: group". (Screenshot included)
Edit: I had a hunch that the different error was because of some other problem, and it was right. The error never happened again. :/
I have deleted and re-installed Minecraft several times since servers stopped working, but nothing changes.
How can I get servers working again?
(I actually contacted Minecraft about this, and had to wait 10 days to get a reply that the support team I contacted was for Billing and Support, and that I would need to contact somewhere else to receive a proper answer. ack!)
I tried running the Minecraft game output, when I was joining servers it didn't say anything but as soon as I started Minecraft it yielded these errors: (screenshot included below)
Strange. The advice I can find says to delete everything in your .minecraft folders except the save folder (where your worlds are stored, don't delete that, or better yet, make a copy somewhere just in case) and reinstall Minecraft from scratch. If that doesn't work, then install Java separately and make sure the settings in the Minecraft launcher are set to use that version and not the one that comes with Minecraft.

To tell them how to live is to prevent them living.
Not sure about the other message you get, but "java.lang.NullPointerException: group" is most commonly related to another program preventing the game from working. Check the list here, https://minecraftirc.net/support-articles/known-incompatible-software/ if you find that you have nothing on that list run a program like ADWCleaner then Malwarebytes.

I saw a post that had the same problem as me, (There are NO other posts describing the same problem as mine.) http://www.minecraftforum.net/forums/support/unmodified-minecraft-client/2783918-server-error-internal-exception-java-lang-error

PROBLEM IS SOLVED! I used the old launcher (https://minecraft.net/en-us/download/alternative) and it worked.
