Currently hitting

Error: node: failed to start: fetching block by hash : rpc error: code = Unimplemented desc = unknown service tendermint.rpc.grpc.BlockAPI

which should be resolved by #4580

[chatton]

@rootulp did you end up getting around the unregistered BlockApi?

[rootulp]

Put this on pause to address other issues. Just resumed and hit this again on the bridge node

Error: node: failed to start: fetching block by hash : rpc error: code = Unimplemented desc = unknown service tendermint.rpc.grpc.BlockAPI

[rootulp]

Error: node: failed to start: fetching block by hash : rpc error: code = Unknown desc = nil block meta for block hash []
