I'm interested in ELLA for writing the smart contracts as exercises because the ETH is hard to sync for a very long time and need a big hard disk. I just start the command "parity --chain ellaism" to sync and happily seeing the fast snapshot sync. The party UI also works well. But only 1/25 peer is connected and I see a message as follows:

"You are connected to only one peer. Your node might not be reliable. Check your network connection."

After adding nodes to ellaism.json, the connection number is only 2. Where is the json which can connect to all as possible?
