It looks like it's still downloading. See the PART file? That's FIrefox's partially downloaded file that gets renamed to the downloaded file upon completion. Also the Size of the installer is being reported as 0 KB.

Split thread, please don't hijack other people's threads.

The issue with the windows message doesn't make sense. As for the jar version it sounds like you don't have Java installed, please install Java 8. (No, having Minecraft running properly doesn't mean you already have Java installed, Minecraft ships with Java but doesn't install it to the point where your computer would recognize it)

Locked. Lex has already expressed his displeasure at messages like this and I am tempted to start applying warning points (and thus punishments) for posts like these. I updated the announcement specifically to alleviate ETA requests, read it and use the links to track Forge's progress. (No I am not part of the dev team, I am using these same resources to track the development progress.)

Where are you getting Forge from?

How did you install Forge?

and there are no errors in the log, right?

Dungeonmod is broken.

Out of curiosity you are talking about ipv4 addresses, right?

No that's usually required for port forwarding to work, what I'm saying is check your public IP again to see if it's changed.

If you changed it in your router it's your private IP, if you called your ISP and added it to your service package it's your public. Unless you have business internet with servers on premises you probably have a dynamic public IP, so it's not out of the question that your public IP may have changed when you restarted it after port forwarding.

Do you have a static public IP or Dynamic DNS?

Only the crash from today is available and it indicates that the server saw itself freezing and decided to shut down before it got worse. You may be hitting the ceiling with your RAM usage, that's not the direct cause according to the log but it might be taxing Java itself trying to keep things within acceptable bounds. Beyond that I can only wonder what your host is giving you for your money in terms of a processor.

You may have it installed, but this error indicates your computer is using a Java 9+ installation to run the jar. If you need to have other versions of Java installed your other option is to specify the full path to the Java 8 java.exe rather than just invoking java.

You must use Java 8

Why are you trying to run Minecraft using a Virtual Machine?

From the quick look that I've taken, it is a JavaScript API (No, JavaScript and Java are not the same language). It appears to be closer to Sponge's Plugin API than Forge's Mod API, although there is a client component to it (unlike Sponge's Server-Only implementation) I don't see any reference to creating your own blocks, items, or entities. I doubt modders will "switch" as you are suggesting, as Forge (and Java by nature) allows mods to access pretty much all of Minecraft's code and resources, whereas with bedrock's scripting API, you will only have access to what the scripting engine gives you access to. I expect even those who do decide to try the scripting API will do it in addition to, rather than instead of, their Forge projects.

1.8.9 is no longer supported on this forum due to its age. Please update to a modern version of Minecraft to receive support.

Did you check the logs folder?

I can't give you an answer without more information...

Please read the "Logs" section of my signature.

Please keep this forum in English. 1.7.10 is no longer supported on this forum due to its age. Please update to a modern version of Minecraft to receive support.

I'm afraid I can't do much more without troubleshooting the server myself. Java is being allowed through your firewall, right? Again, this poses a big risk.
