Hi I'm installing minecraft server version. I installed forge directly but it showed "Downloading minecraft server failed, invalid checksum. Try again, or manually place server jar to skip download". So I downloaded server.jar manually and tried it again, then it said "Failed to download version manifest, can not find server jar URL.". How can I fix this? minecraft_server.1.18.2, forge 40.1.54

here it is

There is something wrong with your network connection or the server is not responding properly.

From the message, it is one of Mojang's servers.

Boilerplate:

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com  You should also read the support forum sticky post.

Problem solved.

IT IS the internet problem.

Eventhough it failed when firstly install forge server/client, a folder named 'libraries' created in the target folder. Specifically, \libraries\net\minecraft\server, and it's empty.

Download official file server.jar from https://www.minecraft.net/download/server or other sources and put it in '\libraries\net\minecraft\server', rename it as 'server-x.xx.x.jar’ (for me it's server-1.18.2.jar).Restart install and everthing goes fine.

if it stucked at downloading mojmaps, just wait or try VPN.

    • should the changes apply only to the listed ores, or do you want a more comprehensive overhaul of resource progression?
    • The information provided isn’t quite enough to pinpoint the issue. It would be helpful to know more about your setup. For instance, what screen recording software are you using, and is it set to capture the game window, full screen, or your entire desktop?
