I have running stellar core and stellar horizon together. Sometimes (recently even more) I am receiving such a response when trying to push tx to the blockchain. How could I approach this issue or prevent it form happening in the future? Appreciate any hint.

Timeout happens when Horizon did not receive an update for a given transaction submission from Stellar-Core. This can happen because of two reasons:

  1. Transaction was not included in the ledger for 30 seconds. This usually means that the fee was too low.
  2. Less likely: Stellar-Core lost sync with the network after transaction was submitted. In such case Stellar-Core issue should be resolved. It's possible that the problem is temporary (ex. one of the nodes in the quorum set is down so there is no consensus).
