Incompatible Vanilla Server

[Burstgaming]

Hello, I decided to start a Minecraft Forge Server with the Crucial 2 Modpack. So I downloaded the server file and followed the readme file. Then I had the first issues:

1. The readme tells me to open the forgeserver.jar which doesn´t exist (there is only the minecraftserver.jar )

2. Sometimes the server is working but it says Incompatible FML Modded Server

 but the most time it´s not working and just says Incompatible Vanilla Server and by joining the Server Incomplete set of tags recieved from server (in the second case the server log looks like that: sending a screenshot is hard as f*** but here is a quick copy-paste:

You need to start the forge jar which is provided.

I have a forge file which I thought doesn´t work... but I just needed to wait 20 seconds

I think sometimes patience is worth it... But I wasted 2 hours for this problem.

Thank you for the quick and right answer.

run the forge jar from the console and post the output
