TileEntity

Yes - not all mods are working on a server (client-side-only mods) - shader mods, minimaps, mods making HUD changes etc

Just check for trending modpacks Maybe ATM9 https://www.curseforge.com/minecraft/modpacks/all-the-mods-9/files/7097953

Same issue Maybe switch to a pre-configured modpack - most of these already have a serverpack Use such a modpack as working base and add some mods

Just replace Connector with this build: https://www.curseforge.com/minecraft/mc-mods/sinytra-connector/files/5761411

Try older builds of Connector

Make sure you put this file into the mods-folder: https://www.curseforge.com/minecraft/mc-mods/fabric-api/files/8443275 Referring to the log, this mod is not present

Maybe sodium addons can fix it - add https://www.curseforge.com/minecraft/mc-mods/sodium-options-api and https://www.curseforge.com/minecraft/mc-mods/dynamiclights-reforged

Does it work without Iris?

Make a test without the mod distraction_free_recipes - looks like it runs into a conflict with JEI Maybe EMI is required, too

Add the crash-report generated with using spark

Aah I think Forge just fixed this issue. With an amplifier of 125, you should get a huge amount of health, but Vanilla is limited. Bypassing this limit results in a negative value, which kills you. Forge probably added some functions to catch overflowing values, which I think is essential for modded content

Add the crash-report And which command do you use?

Add the crash-report or latest.log (logs-folder) with sites like https://mclo.gs/ and paste the link to it here

Make a test with another Launcher like MultiMC or AT Launcher

Text2speech is a client-side-only function - not a mod But a mod is using it which is not working on a server

Same issue without this mod?

This looks like a bug with trinketsandbaubles or an item you are wearing with it If you die, a client-side-only function will be fired (text2speech) which is causing the crash

Do the same for the curios-server.toml file If it is crashing again, check the first lines for other mentioned config files and delete these

Add crash-reports with sites like https://mclo.gs/ Delete the fastleafdecay-server.toml in your config folder If there is no such file, check the worldsave, serverconfig folder

Add it with paste.ee or mclo.gs

Make a test with another Launcher like MultiMC or AT Launcher

Also add the latest.log (logs-folder)

Use a new world or re-add ironchest

Make a test without vintageimprovements

Add the full crash-report
