It looks like you're encountering connection timeout errors during the prefect deploy command. Here are some steps and solutions that might help: 1. Connection and Network Errors: Connection errors can occur for various reasons, including network issues, server-side timeouts, or even misconfigured security groups or firewalls. 2. Read and Write Timeouts: These errors have been documented in Prefect issues and can be due to large data sizes or server-side issues: - Issues often originate from the HTTPX library, which Prefect uses for HTTP requests. - Adjusting the HTTPX read and write timeouts might help alleviate this problem. Example Issue: https://github.com/PrefectHQ/prefect/issues/12838 3. Intermittent HTTP2 Connection Errors: There are known intermittent connection errors with long flow runs, notably with HTTP2 connections. Example Issue: https://github.com/PrefectHQ/prefect/issues/11660 4. Flow with Retry Delay: Multiple invocations of state hooks and automations can occur during retry scenarios, which might affect the network calls. Example Issue: https://github.com/PrefectHQ/prefect/issues/11233 5. SSL Connection Handling: Sometimes unclosed or improperly closed SSL connections can cause issues, prominently seen during testing phases. Prefect Documentation on Troubleshooting Connection Errors: https://docs.prefect.io/latest/guides/troubleshooting/ Prefect Documentation on Deploy Command: https://docs.prefect.io/latest/guides/prefect-deploy/ Actionable Steps: - Increase Timeout Configuration: Consider increasing the HTTPX client timeout configurations in your Prefect deployment to handle longer-running connections. - Check Network Configuration: Ensure all network and firewall settings are appropriately configured for Prefect communication. - Review Logs: Look into the Prefect server logs and relevant flow run logs for more specific error messages which might give more clues. If these steps do not solve the issue, providing specific sections of your error logs might help in providing a more targeted solution.
