[Ethereum] Can’t join nodes/peers to private network

OBJECTION to duplicate problem: The supposed duplicate answer DOES NOT work. The problem wording is similar but the problem itself requires a different solution.

I created a local private chain like below

geth --genesis ...CustomGenesis.json --verbosity 6 --datadir ...customchain1\chain --identity SomeChain --blockchainversion 12 --networkid 123 --rpcport 8101 --maxpeers 15 console 

Launching the wallet, I have to skip peer search because it never finishes. After opening I can see I'm in PRIVATE-NET but with 0 peers.

I noticed I needed 12 peers for validation of contracts so I tried creating 1-2 nodes to see if this would work. I used below tutorial and some others I forgot.

https://github.com/ethereum/go-ethereum/wiki/Connecting-to-the-network

Initially, I created another folder with geth.exe in it. then used the below command on a seperate console while the main geth.exe was already running.

geth --datadir="...\customchain1\node1\chain" --verbosity 6 --networkid 123 --ipcdisable --port 30302 --rpcport 8102 console

I used admin.nodeInfo.enode on the node geth console to get enode value. Then used below command on the primary geth console to add as peer.

admin.addPeer("enode://7a68ad5995ed4fa02a20f582e0c41bd6afad609102edda3fe3b443b618e56b11282d78cbeddfd2b8fb846a36ed6230d446fb41dc5fd77ff97bf20502e7ce0568@[::]:30302")

EDIT Adding " before and after enode returns true but admin.peers returns nothing still.

This returns (anonymous): Line 1:20 Unexpected token :

I then copied the genesis file I used to create the blockchain, deleted everything else and ran the exact same command within the node folder. I retrieved the enode line and tried again. The error was the same.

Am I misunderstanding how this should work or is there something else I'm missing?

Thank you.

EDIT Almost There Some logs I captured. Seems that they do almost connect then drop due to mismatched networkID but where the hell does it get that number from? I have nothing with networkID 1602902873 and I explicitly state the networkID differently in all commands.

SHAME…SHAME…SHAME…bell rings
So while trying to understand how a random magical networkID appears instead of the one I gave. I noticed it was an Integer if written without quotes. I had a number beyond the max int value. When I fixed it to something acceptable it worked immediately.
