KubeJS script suddenly times out server
Minecraft version: 1.20.1 Fabric
Hello! I did inquire about this on the KubeJS Discord yesterday, but so far no one has responded to it yet. My script used to work, but is now crashing the server and I have not changed it. I'm not sure that the KubeJS script is actually wrong - but if there is a bug or another issue, I could use the help pinpointing what's actually going on. My script has no parsing errors in Visual Studio or when loaded with KubeJS.
The script is a chat command that checks if the player has
whimsy.prefix.phoenix
before removing other cosmetic ranks and then giving them the phoenix rank with LuckPerms if they do have the permission, or telling them that they don't have the required permissions if they don't have the permission....Wild Connection issues with direct IP
When I join my server with the direct IP there are wild connection issues across the board (slow joining time, MASSIVE lag spikes, etc). But when I join using the domain there are no connection issues. Does anyone know why this might be happening?
Replace mob
Is there a way to replace a mob and mob spawn for example turn all sheep spawns into spider spawns so theres large patches of spiders and no sheep
Starting a Minecraft Host
Hey all, what kind of specs should I get? We're starting off in an invite-only beta and onboarding will be slow to start. We want to start off with an EU location
Currently, I'm look at a 7950x from Pebblehost + cosmic guard, unsure of how much storage/ram would be required. This is strictly Minecraft hosting and all backups are off-site.
No specific budget in mind, just an overall good spec machine that will last us through out beta. We plan on buying more machines in the future obviously....

How to properly switch back from Nukkit to BDS but keeping old world and player data
As title. I did try move world folder to the BDS one, but when I join, the server crashed with error "Worls corrupted", and when I restart the server and join the server, the world and player data are wiped but the seed remained.
custom block textures? mc 1.21.3
i have tried using custom model data on blocks and it doesnt work, as expected. i have heard that you can make a datapack that summons an item frame with the custom texture on a vanilla block, but this causes entity lag and is difficult to pull off. i need an easy alternative to this for my server. i know it is possible because plugins like myfurniture do things like this, but is it because it uses blue candles? or is it still using the item frame trick? also, the item frame trick doesnt let you...
FTBTeams permissions issue?
I'm losing my mind on this, for some reason, nothing is allowing ftbteams to let non-opped players to access it's commands. I've tried adding it's commands to ftbranks to no avail. When I'm not opped it says Server Permissions blocks it. What is the deal with this?
It's on the Star Academy Modpack, Minecraft 1.20.1 Fabric. I'm not sure what could be blocking the permissions from being given to the average player...
Best way to host a network
Hello! I’m planing to develop a Minecraft SMP which I’d like to release globally. I’ve been watching Donut SMP and I really wanted to know if someone knows how those kind of servers work or how to make a similar network and where can I make it based on quality/price.
I want to make a testing for 40-50 people and later on improve to way better options, but I’m really interesting to know how can I make a SMP with multiple servers in different regions like Donut SMP does or similar but in europe.
Sorry if I the explanation isn’t that good but english ain’t my 1st language....
Quick question about Spark Regions
How do I know what region is Region #1 vs Region #2 on the sprak profiler report?

connection timed out
Hey I just setup a modded server (self host) for a few friends but they can't join the server. I can join the server on my wifi and it runs completely fine. I swear I port fowarded the ports needed on the machine and router. Did I miss something?

Wanting to start an open server from my old computer
Hello y'all, so recently ive been having an itch to revive a minecraft server that died a few years ago. This would be my first time hosting a minecraft server, let alone one that might get 20 ppl on at the same time. So, if its not too much to ask, is it possible that i could get a rundown on everything that i would need to know to run the server on my old pc? (ryzen 5 3600, 32 gigs RAM) Should i be concerned about network security? (as it would be run from my house network).
Thanks in advance...
Weird entity lag in fabric with 20 tps
So i have a vanilla (as in no content mods or whatever) fabric server and after downloading some optimization mods to help with the server tps (which, to be fair, barely improved it) I am now faced with a new issue. Even with only 2 people on the server, there is some kind of lag going on, but not tps lag, just every entity has some delay between movements, be it an axolotl or a player, they just dont move smoothly like before.
Im currently thinking it might be one of the mods, but i cant figure it out for the life of me what would cause this.

Corrupted Heightmap Data (?)

Custom commands help
Hey, I'm using commands.yml and custom.txt with Essentials to do custom commands, its easy to create a custom command that just returns text like a link or such, but I'm not sure how I can make a custom command that makes the player enter a command directly instead of just showing them text, I know it's possible, just not sure of how, any help?
Mobs barely spawning, modded 1.20.1 Forge server
I'm hosting modded server (30-40 players online) and for some reason (probably my low knowledge) there are no mobs spawning at all when away from spawn T_T
You can see my screenshots, first is 1k blocks away and second is14k blocks away
Some useful info for you:

Hosting Alternatives
need some leads to other hosting options. we have Bloom as our first option as we have tried their service before. Bloom is great but we're just curious if we're missing out on other great (maybe cheaper) options.
what we need:
- hosted in Singapore
- 8-12gb of RAM
- atleast 100gb of storage...
CPU choice
What is a good way of measuring cpu performance for minecraft servers?
I'm in the middle of buying a homelab server. On it I'll be hosting most likely max 2 servers
First one for big modpacks - max 5 players
Second one vanilla with some plugins (dynmap for example) - also max 5 players
