Can not add peer in local ethereum blockchain

Question

I am trying to add one node to my local ethereum , I am running the first node with :

geth --port 30303 --networkid 1234 --nodiscover --datadir ethereum/paradox --rpc --rpcport 8545 --rpccorsdomain "http://localhost:8000" --allow-insecure-unlock --ethstats paradox:s3cr3t@localhost:3000 --rpcapi "eth,net,web3,personal,miner"

My Second node with :

geth --datadir "$ethereum_home/sample" --nodiscover --networkid 1234 --port 30304

they both points to the same genesis block.

When i run the command "address" it returns true but the It does not show peers when I run "admin.peer"

My genesis file:

{ "config": { "chainId": 4224, "homesteadBlock": 0, "eip150Block": 0, "eip150Hash": "0x0000000000000000000000000000000000000000000000000000000000000000", "eip155Block": 0, "eip158Block": 0, "byzantiumBlock": 0, "constantinopleBlock": 0, "petersburgBlock": 0, "istanbulBlock": 0, "ethash": {} }, "nonce": "0x0", "timestamp": "0x5f350017", "extraData": "0x0000000000000000000000000000000000000000000000000000000000000000", "gasLimit": "0x47b760", "difficulty": "0x80000", "mixHash": "0x0000000000000000000000000000000000000000000000000000000000000000", "coinbase": "0x0000000000000000000000000000000000000000", "alloc": { "0000000000000000000000000000000000000000": { "balance": "0x1" }, "00000000000000000000000000000000000000ff": { "balance": "0x1" } }, "number": "0x0", "gasUsed": "0x0", "parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000" }

The interesting thing is when I stop both nodes and restart again and then do "address" it shows another node in the peer array but just for a second and if I run command admin.peer it shows noting

You have port 30305 running in your lines for one node, and 30303 for another. Why have you tried addPeer with port 30304? Check the availability of the ports listed on the command line while running the instances and also check correctly the node key and port.
