Describe the Bug

I have made a dedicated server and a client with just the Create mod, it seems that with it I am unable to connect to the server, however if I remove the Create mod from both I am able to connect to the server (and with any of the other mods I use). I am on the latest build 0.4.0d+254

I see no errors on either side and I do in fact connect, however as soon as I connect I am immediately disconnected.

Reproduction Steps

1. Set up a dedicated server with Fabric API and Create
2. Make a client instance with Fabric API and Create
3. Join the server (an easy way to do this without port forwarding is to use ngrok https://ngrok.com/)
4. The client should go through all steps up to "Joining world.." until it abruptluy goes to a screen saying "Connection Lost"

Expected Result

I am able to properly connect to the server and play.

No response

This appears to be a local server issue only: #213

Add Priority to this thread because this is a fairly serious issue

Please install WDMNF on both server and client, try again, and send both new logs.

Okay it appears the 1.17 version worked (probably because 1.18.1 still uses Log4J but 1.18.2 uses SLF4J) so here are the server and client logs:

Updated server log: https://pastebin.com/4dTzMY2q
Update client log: https://controlc.com/3ab1eaa8 (pastebin kept deleting my log for some reason)

still happening with latest build

OK I have manually built from source (I am trying to make a PR to fix this)

Here is a better quality (non-obfuscated) log of the error: https://pastebin.com/h5HgBHV2

potential_fix.zip
This jar has a modified port lib jar. Add this to your mods on client and server and test. This will be broken in many other ways, I removed some possibly problematic code, so don't use it on anything important. Provide logs after.

Okay I think I got it to be the used porting_lib (I am using modImplementation files("../porting_lib-0.2.0-interfacent+1.18-interfacent.cfd1087.jar") to import it and I am doing a custom build off of the source). I still can not connect, here is the log it is giving me: https://pastebin.com/PjVXs9GW

can you provide a full log?

Client: https://pastebin.com/NrhSL5w4
Server: https://pastebin.com/nmTXxH0u
(Server has online-mode turned off so I can connect to it to the local project)

This exact same thing happens to me as well. Any news here?

this might be related to #194, but I have zero ideas for either issue.

Well I can tell this happens on a new fabric server, only the Fabric Api and create mod installed.
When I create a singleplayer world, it works as expected.

A little addition: The same error occurs, when only the client has the mod installed and it's trying to connect to the server. I would expect a mod mismatch error, but instead the client disconnects immediately. Maybe this helps finding a solution

This appears to be a local server issue only: #213

I don't think it is only localhost server issue.
I have the same problem with my client being on my laptop and the create server being on a dedicated station.

Is it on the same network as the client?

nope
my mc server is deployed on my cloud server with a public IP

This client log has been removed, can someone provide a new one?

Same here

Currently not tested with this fix BTW, should it be used?

It probably won’t matter but there’s no harm in it

I'm having issues launching with WDMNF, is it a mod you drop in the 'mods' folder?

Yes. Make sure you use the 1.17 version.

My bad, going to

Yes. Make sure you use the 1.17 version.

Okay, personally I barely got any special logs, hope it helps :(

Client: https://gist.github.com/drakes00/5814767c03531fa992311ba64ec9e44a

I'm surprised I didn't got the special character related error someone had up there

Is there anything needed to assist with solving this issue?

Is there anything needed to assist with solving this issue?

I personally have no idea on how to solve this but I can help providing feedback if it helps :(

I'm inclined to believe that create (when on the server) possibly doesn't register probably like 1 line of code correctly and doesn't sync correctly or another way around. Or perhaps a remnant piece of code was leftover from an old syncing system and interferes with server-client compatibility. My idea is that there is no syncing because maybe 1 block doesn't register in either the client or the server and due to undeveloped logging, it is impossible to find what block/entity is causing the issue.
Idk I'm just throwing out random ideas to see if it might help to solve this issue.

I am using the Build 441 now, because I have read that this is the most stable one. It works for me, also with connecting to the server. Maybe this helps finding the problem

I narrowed the issue down to a commit after e4c7c73 up to b5fc151 in Porting-Lib.
