having troubble getting friends onto a server i created. i set the ip to my IPv4 but he still cant connect, and i have port forwarded. i CAN however get into the server with the ip on my second computer. did i mess up the port forwarding? this is the version im using. forge-1.10.2-12.18.3.2316

scratch my last, now it crashes when i try to run the server https://gist.github.com/anonymous/839a247632943ef849d315c47c473e8a

well maybe you can help me with anotherone. i tried another mod pack that uses a much newer version. was wondering if you could help me with that.

i mean thats the version it uses so idk what to do

where do i find that? you mean the crash reports? (edited) i think i found it https://gist.github.com/anonymous/6a91a102ee2c08793de2ec51fcf464cb

having another problem. when i try to connect to my server i get a connection lost error. goes like this internal exception: java.lang.illigalargumentexception: the object block(ic2:sappling)(62e84527) has been registered twice, using the names null and ic2:sapling. (other object at this id id null{0}) Does anyone know how to solve this issue? already tried deleting and running it again (to get it back) but i always get this issue.

if im trying to make a server do i need to download a client and server into a new folder?

im using the twitch/curse client for modded minecraft. Whenever i try to make a modded server using forge, the server for my ftb mod pack infinity evolved, the server always crashes. ive tried a number of other mod pack (and yes i'm using the right versions i've triple checked) i know it has to do with a bad mod or somthing, bc the server will run before i transfer over any mods into the "mod" folder. is this program garbage or somthing? nothing seems to work besides going through every single mod. and rooting out the bad mods. but on twitch it says it should be compatable with the forge version im using. am i doing somthing wrong? ive been working at this for a while now and its become extreemly frustrating. what if i wanna use 2 mods that require 2 differant versions? i just dont understand why none of this shit is working. can anyone help explain how this all works? and yes ive accepted the eula or whatever by typing in true.
