Timeout

If you are encountering this error it means that either:

• Horizon has not received a confirmation from the Core server that the transaction you are trying to submit to the network was included in a ledger in a timely manner or:
• Horizon has not sent a response to a reverse-proxy before in a specified time.

The former case may happen because there was no room for your transaction in the 3 consecutive ledgers. In such case, Core server removes a transaction from a queue. To solve this you can:

• Keep resubmitting the same transaction (with the same sequence number) and wait until it finally is added to a new ledger or:
• Increase the fee.
