you are running a single player open to lan server?
BerryRainy
BerryRainyOP3mo ago

Tamz

what modpack
BerryRainy
BerryRainyOP3mo ago
its BigChadGuys Plus (w Cobblemon) with a couple extra mods i added that were cobblemon related
Tamz
Tamz3mo ago
ok it might not work then. BCG+ uses a mod that lets you host outside your home network. and typically its not safe to host big modpacks in singleplayer lan
BerryRainy
BerryRainyOP3mo ago
ahhhh
Tamz
Tamz3mo ago
what are your pc specs? id assume its decent to run a single lan to your gf
BerryRainy
BerryRainyOP3mo ago
its a i5-13600k 3060ti and 32gb ram
Tamz
Tamz3mo ago
perfect you can run a Actual local server and have it open to lan automatically ill teach you how its far safer and actually way nicer then single player lan

then let its do its thing downloading stuff and working to launch you will also need to add the custom mods you added to your client to join. BUT there are mods that are CLIENT ONLY so cannot be added to servers
BerryRainy
BerryRainyOP3mo ago
okay i understand that part the mods i added should be on the server they dont say they are client side
Tamz
Tamz3mo ago
they should be client+server mods mods that need be on both you can type the word list inside of the cmd that the server pack opened and if it says something like this [Server thread/INFO]: There are 0 of a max of 20 players online: then the server is started you can join the server with localhost as the ip while ur gf when connected to the router can connect via the IPV4 of your pc to check what it is, go to cmd and type ipconfig then the ipv4 address
BerryRainy
BerryRainyOP3mo ago
what if the mods dont say server or server and client do i add those as well
Tamz
Tamz3mo ago
like what mod?
BerryRainy
BerryRainyOP3mo ago
like JEI
Tamz
Tamz3mo ago
that belongs in the server
BerryRainy
BerryRainyOP3mo ago
okay cool
Tamz
Tamz3mo ago

BerryRainy
BerryRainyOP3mo ago

Tamz
Tamz3mo ago

BerryRainy
BerryRainyOP3mo ago
okay i think i have moved over the mods to the server side or copied them over
Tamz
Tamz3mo ago
if it doesnt work itll crash so dw
BerryRainy
BerryRainyOP3mo ago
haha okay
Tamz
Tamz3mo ago
its not a bad thing as it means somethings wrong
BerryRainy
BerryRainyOP3mo ago

Tamz
Tamz3mo ago
:thumbsupcat: when you are saving the server you need to do the command stop
BerryRainy
BerryRainyOP3mo ago

Tamz
Tamz3mo ago
:thumbsupcat: and the command will auto stop the server too when its all done
