cardano-cli query tip --mainnet
cardano-cli: QueryEncoderUnsupportedQuery Query GetSystemStart TopLevelQueryDisabled

I'm trying to get the current tip(slot) for my my transaction ttl.


cardano-cli query tip --shelley-mode --mainnet
Command failed: query tip  Error: Unsupported mode: ShelleyMode

after i added --shelley-mode flag, it still doesn't work.

  • Can you try running the query with --shelley-mode flag?

You're not using the release version, which - for 1.27.0 (current mainnet) - is 8fe46140a52810b6ca456be01d652ca08fe730bf.

Using commits later than current stable release should only be done if you're sure if a specific commit is compatible and works - and should be done on testnet instead
