[RESOLVED] Unable to log in to LAN server - Missing registry data for network connection

[Aevaris]

Hi all,

 

Every time I upgrade mods, I seem to run in to this error with my LAN "server". The offending log entry seems to be below:

[10:31:01] [Render thread/INFO] [minecraft/ConnectingScreen]: Connecting to 192.168.86.246, 52432

[10:31:04] [Render thread/ERROR] [ne.mi.re.GameData/REGISTRIES]: Unidentified mapping from registry minecraft:block

chiselsandbits:bit_tank: 5733

chiselsandbits:chisel_station: 5734

rangedpumps:pump: 1233

 

[10:31:04] [Render thread/ERROR] [ne.mi.fm.ne.FMLHandshakeHandler/FMLHANDSHAKE]: Missing registry data for network connection:

minecraft:block: chiselsandbits:bit_tank

minecraft:block: chiselsandbits:chisel_station

minecraft:block: rangedpumps:pump

 

[10:31:04] [Netty Client IO #0/ERROR] [ne.mi.fm.ne.FMLHandshakeHandler/FMLHANDSHAKE]: Failed to load registry, closing connection.

[10:31:04] [Netty Client IO #0/ERROR] [ne.mi.fm.ne.FMLHandshakeHandler/FMLHANDSHAKE]: Connection closed, not continuing handshake

 

Some details:

Minecraft 1.16.4

Forge 35.1.15

MultiMC launcher

 

In my Googling, I've found this is often due to either client or mod files being out of sync. I copy and pasted both directories across both computers. I also tried using the java argument -Dfml.queryResult=confirm with no success. Interestingly, the rangedpumps mod is actually disabled entirely. Is this something that can be fixed on my side or is this representative of a mod problem? Is there a means to re-register/remove the offending entries/blocks?

 

Thanks for your help all!

What do you mean by "LAN 'server'"?

Do you mean a dedi on your local network or do you have a client running with LAN open?

[Aevaris]

Client running with LAN open.

 

Edit: In poking through the logs on the client host (the client with the LAN open), I see the entry in the logs I expect of "the following IDs can't be found and will be removed" but it doesn't seem to actually remove them which is weird and then proceeds with a "found unidentified IDs, loading anyway" message.

Would my options improve if running as a server? I've been toying with the idea of building a VM for the purpose of running as my Minecraft server.

[DaemonUmbra]

Why would you need a VM? That would just add extra overhead.

You can just install and run the server.

[Aevaris]

I already have a VM running on an old PC for Emby, so I'd spin one up on the same physical host. That host already runs 24x7, so it can stay running while our computers can sleep / play other games, etc. It'd be a small overhead for Minecraft but increased convenience.

 

This is my first 1.16.4 play of minecraft. Upgrading mods have never given me trouble in the past. I should note that things work fine if the server loads with the mods, its only when the mods change that I have the issue. Is there a way to force re-registering of the blocks in 1.16.4?

 

Edit: But I see your point, realistically, we'll only play minecraft for a few weeks at a time, so having a VM for it seems clunky and instead could run the server client locally instead. I'll think/play around with that idea.

So I set up a local server (using the actual server client and not a LAN-opened SP client) and am getting the same issue. Attached is the server latest log and debug log. The debug log is too large for pastebin or here (its ~2MB), so it is split up into multiple files.

 

I am going to attempt some other things to see if there is any fix, but would be interested if the logs tell anything useful or if there is a way to fix this on my side (or if this needs to be a bug report somewhere).

 

In this log, the only change I made was an upgrade to chiselandbits from 0.2.2 to 0.2.8. This is also with the server running forge 35.1.28.

 

Interestingly, this isn't working:
"There are 4 missing entries in this save.
If you continue the missing entries will get removed.
A world backup will be automatically created in your saves directory."

 

Neither the backup is created nor are the entries removed.

Update. Fascinating. I passed in "--forceUpgrade" when launching the server and this seems to have resolved my problem. I can now connect the client to the server. Is this something forge or minecraft handled automatically previously? I've never had to do something like that before.

 

Edit: Adding some copy-pasta for Google that I used when researching my problem in case this helps posterity. None of the posts/info I found out there helped me, so maybe this can help others in the future. I don't see a spoiler feature on this forum, so pasted below.
