We are having issues with
RPC & Collator nodes connecting to
Rococo relaychain. The running chain works but once we restart any node, it cannot find relay peers on the
relaychain and thus
stalls / stop syncing. We noticed just recently because we restarted some nodes.
For any other Project having issues with connecting to the Rococo relaychain please check if you are using old relay-chain bootnodes on your collator (due to importing old polkadot). We would recommend you override it with the latest rococo chainspec. By using
-- --chain chainspec.json and using this file https://raw.githubusercontent.com/paritytech/polkadot/master/node/service/chain-specs/rococo.json
