[Updated] Minecraft server down or not working (unable to play multiplayer), issue acknowledged

Here is the crux of the article in video form:

New updates are being added at the end of this story…….

The original story (published March 30, 2022) is as follows:

Minecraft is a popular open world sandbox game where you have to explore, survive and build.

Minecraft’s construction system is full of possibilities, being one of the key aspects of the game’s success. The internet is full of massive construction projects of all kinds, from buildings to entire worlds.

On PC, Minecraft is available in two versions: Standard (or ‘Bedrock’) and Java Edition. Minecraft Java Edition is available on Windows, Mac, and Linux.

You can expand the possibilities of Minecraft: Java Edition through Forge, which is a server that improves the compatibility of the game with mods.

That said, many Minecraft: Java Edition players are facing a crash issue where they receive an ‘Exit Code -1’ error message when using Forge mods (1, two, 3, 4, 5, 6, 7, 8).

Minecraft: Java Edition crashes or throws ‘Exit Code -1’ on Forge mods

According to various reports, using Forge mods is causing a crash issue, “Exit code -1” error message, or “Java runtime configuration may be invalid” error message for many players of Minecraft: Java Edition.

Hi, I’m trying to play modded 1.18.2, but when I try to start the game with any mod besides the ones installed and launched with forge, it will fail with an exit code of 1 and say the java runtime config can not be valid. I have reinstalled minecraft, java and even downgraded the forge version but nothing works.
Font

Some face the problem without Forge mods as well

In some cases, players who do not have any Forge mods installed in Minecraft: Java Edition (1, two, 3, 4, 5, 6, 7, 8).

Exit code: 1

Every time I try to start Minecraft I get a screen that says Invalid Java Runtime Configuration” “Exit Code 1” I don’t have any mods or forges downloaded, it’s just plain vanilla. I downloaded Minecraft before I downloaded Java, if that matters. I also get a screen that says “a java exception occurred”. Any help would be appreciated.

Additionally, some players are suggesting that all versions of the game (from 1.7.10 to 1.18.2) could be affected.

A possible explanation and solution.

The problem could be related to the version that the mod you installed was developed for. To avoid problems, you should install mods only on the version of the game for which they were developed.

Overview: Always be prepared for bugs when your mods are not for THE EXACT version you play. For example, 1.18.1 mods might not work for 1.18.2 and vice versa.
Font

The version of Java on your PC could also cause problems. It seems that you should only install the latest versions of Java for versions of Minecraft greater than 1.16. For versions of Minecraft prior to v1.16, you will need to use Java 8.

This could be the cause:

Latest Java = 17 -> for MC 1.16+

For older versions of MC, use Java 8
