Hello, Today i tried the recommended one instead of the latest one and now the server is starting. I didn't change anything, so I guess the problem for me is or was in the latest one. So problem solved. Regards, Erik

Hello, i have a fresh install of Forg on my computer which is running OpenSuse Tumbleweed, java version 8. The installer went fine but the starting part, without mods, has some troubles. java -Xmx1024M -Xms1024M -jar forge-1.15.2-31.1.60.jar [20:34:38] [main/INFO] [cp.mo.mo.Launcher/MODLAUNCHER]: ModLauncher running: args [--gameDir, ., --launchTarget, fmlserver, --fml.forgeVersion, 31.1.60, --fml.mcpVersion, 20200414.225201, --fml.mcVersion, 1.15.2, --fml.forgeGroup, net.minecraftforge] [20:34:38] [main/INFO] [cp.mo.mo.Launcher/MODLAUNCHER]: ModLauncher 5.1.0+69+master.79f13f7 starting: java version 1.8.0_242 by IcedTea [20:34:38] [main/INFO] [ne.mi.fm.lo.FixSSL/CORE]: Added Lets Encrypt root certificates as additional trust [20:34:40] [main/INFO] [cp.mo.mo.LaunchServiceHandler/MODLAUNCHER]: Launching target 'fmlserver' with arguments [--gameDir, .] [20:34:52] [main/WARN] [minecraft/Commands]: Ambiguity between arguments [teleport, destination] and [teleport, targets] with inputs: [Player, 0123, @e, dd12be42-52a9-4a91-a8a1-11c01849e498] [20:34:52] [main/WARN] [minecraft/Commands]: Ambiguity between arguments [teleport, location] and [teleport, destination] with inputs: [0.1 -0.5 .9, 0 0 0] [20:34:52] [main/WARN] [minecraft/Commands]: Ambiguity between arguments [teleport, location] and [teleport, targets] with inputs: [0.1 -0.5 .9, 0 0 0] [20:34:52] [main/WARN] [minecraft/Commands]: Ambiguity between arguments [teleport, targets] and [teleport, destination] with inputs: [Player, 0123, dd12be42-52a9-4a91-a8a1-11c01849e498] [20:34:52] [main/WARN] [minecraft/Commands]: Ambiguity between arguments [teleport, targets, location] and [teleport, targets, destination] with inputs: [0.1 -0.5 .9, 0 0 0] [20:34:52] [Server thread/INFO] [minecraft/DedicatedServer]: Starting minecraft server version 1.15.2 [20:34:54] [Server thread/ERROR] [minecraft/MinecraftServer]: Encountered an unexpected exception java.lang.NullPointerException: null at net.minecraftforge.fml.loading.moddiscovery.BackgroundScanHandler.waitForScanToComplete(BackgroundScanHandler.java:97) ~[forge-1.15.2-31.1.60.jar:?] {} at net.minecraftforge.fml.ModLoader.gatherAndInitializeMods(ModLoader.java:178) ~[?:?] {re:classloading} at net.minecraftforge.fml.server.ServerModLoader.begin(ServerModLoader.java:45) ~[?:?] {re:classloading} at net.minecraft.server.dedicated.DedicatedServer.func_71197_b(DedicatedServer.java:122) ~[?:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:613) [?:?] {re:classloading,pl:accesstransformer:B,pl:runtimedistcleaner:A} at java.lang.Thread.run(Thread.java:748) [?:1.8.0_242] {} [20:34:54] [Server thread/ERROR] [minecraft/MinecraftServer]: This crash report has been saved to: /media/htpc/kinderen/minecraft/Survival-forge/./crash-reports/crash-2020-04-27_20.34.54-server.txt [20:34:54] [Server thread/INFO] [minecraft/MinecraftServer]: Stopping server [20:34:54] [Server thread/INFO] [minecraft/MinecraftServer]: Saving worlds [20:34:54] [Server thread/ERROR] [minecraft/MinecraftServer]: Exception stopping the server java.lang.IllegalArgumentException: Can not hotload overworld.
