When I go to start the server, it crashed before it starts. Originally I thought I had some mods messing it up, so I deleted all the mods, and then all of the forge files, and did a reinstall, but after the reinstall, I still get the same errors. I have copied the stuff that was spit out up until the crash. I changed the error text color to red. java -jar -Xmx6G -Xms6G forge-1.16.3-34.1.42.jar nogui [15:35:41] [main/INFO] [cp.mo.mo.Launcher/MODLAUNCHER]: ModLauncher running: args [--gameDir, ., --launchTarget, fmlserver, --fml.forgeVersion, 34.1.42, --fml.mcpVersion, 20201025.185957, --fml.mcVersion, 1.16.3, --fml.forgeGroup, net.minecraftforge, nogui] [15:35:41] [main/INFO] [cp.mo.mo.Launcher/MODLAUNCHER]: ModLauncher 8.0.6+85+master.325de55 starting: java version 11.0.9 by Debian WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by cpw.mods.modlauncher.SecureJarHandler (file:/opt/minecraft/forge/libraries/cpw/mods/modlauncher/8.0.6/modlauncher-8.0.6.jar) to field java.util.jar.Manifest.jv WARNING: Please consider reporting this to the maintainers of cpw.mods.modlauncher.SecureJarHandler WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations WARNING: All illegal access operations will be denied in a future release [15:35:41] [main/INFO] [ne.mi.fm.lo.FixSSL/CORE]: Added Lets Encrypt root certificates as additional trust [15:35:41] [main/INFO] [mixin/]: SpongePowered MIXIN Subsystem Version=0.8.2 Source=file:/opt/minecraft/forge/libraries/org/spongepowered/mixin/0.8.2/mixin-0.8.2.jar Service=ModLauncher Env=SERVER [15:35:42] [main/INFO] [STDERR/]: [jdk.nashorn.api.scripting.NashornScriptEngine:<init>:143]: Warning: Nashorn engine is planned to be removed from a future JDK release [15:35:43] [main/INFO] [cp.mo.mo.LaunchServiceHandler/MODLAUNCHER]: Launching target 'fmlserver' with arguments [--gameDir, ., nogui] [15:35:56] [modloading-worker-2/INFO] [ne.mi.co.ForgeMod/FORGEMOD]: Forge mod loading, version 34.1.42, for MC 1.16.3 with MCP 20201025.185957 [15:35:56] [modloading-worker-2/INFO] [ne.mi.co.MinecraftForge/FORGE]: MinecraftForge v34.1.42 Initialized [15:35:58] [Forge Version Check/INFO] [ne.mi.fm.VersionChecker/]: [forge] Starting version check at https://files.minecraftforge.net/maven/net/minecraftforge/forge/promotions_slim.json [15:35:59] [Forge Version Check/INFO] [ne.mi.fm.VersionChecker/]: [forge] Found status: AHEAD Current: 34.1.42 Target: null [15:36:06] [main/INFO] [mojang/YggdrasilAuthenticationService]: Environment: authHost='https://authserver.mojang.com', accountsHost='https://api.mojang.com', sessionHost='https://sessionserver.mojang.com', name='PROD' [15:36:08] [main/WARN] [minecraft/Commands]: Ambiguity between arguments [teleport, destination] and [teleport, targets] with inputs: [Player, 0123, @e, dd12be42-52a9-4a91-a8a1-11c01849e498] [15:36:08] [main/WARN] [minecraft/Commands]: Ambiguity between arguments [teleport, location] and [teleport, destination] with inputs: [0.1 -0.5 .9, 0 0 0] [15:36:08] [main/WARN] [minecraft/Commands]: Ambiguity between arguments [teleport, location] and [teleport, targets] with inputs: [0.1 -0.5 .9, 0 0 0] [15:36:08] [main/WARN] [minecraft/Commands]: Ambiguity between arguments [teleport, targets] and [teleport, destination] with inputs: [Player, 0123, dd12be42-52a9-4a91-a8a1-11c01849e498] [15:36:08] [main/WARN] [minecraft/Commands]: Ambiguity between arguments [teleport, targets, location] and [teleport, targets, destination] with inputs: [0.1 -0.5 .9, 0 0 0] [15:36:08] [main/INFO] [minecraft/SimpleReloadableResourceManager]: Reloading ResourceManager: Default, forge-1.16.3-34.1.42-universal.jar [15:36:11] [Worker-Main-5/INFO] [minecraft/RecipeManager]: Loaded 7 recipes [15:36:13] [Worker-Main-5/INFO] [minecraft/AdvancementList]: Loaded 927 advancements [15:36:19] [Server thread/INFO] [minecraft/DedicatedServer]: Starting minecraft server version 1.16.3 [15:36:19] [Server thread/INFO] [minecraft/DedicatedServer]: Loading properties [15:36:19] [Server thread/INFO] [minecraft/DedicatedServer]: Default game type: SURVIVAL [15:36:19] [Server thread/INFO] [minecraft/DedicatedServer]: Generating keypair [15:36:19] [Server thread/INFO] [minecraft/DedicatedServer]: Starting Minecraft server on *:25565 [15:36:19] [Server thread/INFO] [minecraft/NetworkSystem]: Using epoll channel type [15:36:20] [Server thread/WARN] [minecraft/DedicatedServer]: **** FAILED TO BIND TO PORT!

I made a forge server on a linux machine, I can connect to the server just fine, but when I try to use portals from mods, such as ratlantis and underworld, the portals spawn and appear, but when I walk into the portal, nothing happens. But if I go to singleplayer, I can go through the portals just fine.
