Hi @Marvin I am getting the following error while running prefect flows.

aiohttp.client_exceptions.ClientConnectorError: Cannot connect to host <http://hooks.slack.com:443|hooks.slack.com:443> ssl:default [Temporary failure in name resolution]

The error

aiohttp.client_exceptions.ClientConnectorError: Cannot connect to host <http://hooks.slack.com:443|hooks.slack.com:443> ssl:default [Temporary failure in name resolution]

indicates that there was a failure in resolving the hostname

<http://hooks.slack.com|hooks.slack.com>

. This can happen for several reasons: 1. Network Issues: Temporary network issues might be preventing your host from resolving the DNS for Slack. 2. DNS Configuration: Your DNS configuration might be incorrect. Ensure that the DNS server you are using is functional. 3. Firewall/Proxy Settings: Ensure that there are no firewall or proxy settings that might be blocking the connection. ### Steps to Troubleshoot 1. Check Network Connectivity and DNS Resolution: - Ensure your machine has a working internet connection. - Try resolving the Slack webhook URL manually using

nslookup

or `ping`:

bash
     nslookup <http://hooks.slack.com|hooks.slack.com>
     ping <http://hooks.slack.com|hooks.slack.com>

2. Check SSL Configuration: - Verify that your SSL configuration is correct. If you’re behind a corporate firewall, you may need to configure your SSL settings accordingly. 3. Inspect Firewall/Proxy Settings: - Ensure that your network firewall or proxy is not blocking outgoing requests to Slack. 4. Use Reliable DNS Servers: - Sometimes using a different DNS server (like Google’s 8.8.8.8 or Cloudflare’s 1.1.1.1) can resolve such issues. ### Resource Links - Prefect Slack Integration - Prefect Troubleshooting Guide These links should provide additional context and assistance with setting up and troubleshooting Prefect Slack integrations. If the issue persists, you might need to consult your network administrator or further investigate network-related issues on your host machine. Wouldn't it be so wonderful if everything just worked the first time around? Ah, the joys of existence.

@Marvin can you help me with the following error

Of course. Could you please provide the details of the new error you're encountering? The more specific you are, the better I can assist you.

@Marvin this is the error I am encountering

prefect.server.services.telemetry - Failed to send telemetry: [Errno -3] Temporary failure in name resolution

The error

prefect.server.services.telemetry - Failed to send telemetry: [Errno -3] Temporary failure in name resolution

generally indicates that Prefect is unable to resolve the telemetry endpoint's hostname due to DNS resolution issues. Here are the steps to troubleshoot the issue: ### Steps to Troubleshoot 1. Check Internet Connectivity: - Ensure that your server or machine running Prefect has proper internet connectivity. 2. Verify DNS Configuration: - Confirm that the DNS settings on your machine are correctly configured. - Consider using public DNS servers like Google (8.8.8.8) or Cloudflare (1.1.1.1). 3. Test DNS Resolution Manually: - Use

nslookup

or

ping

to resolve the hostname Prefect is trying to reach for telemetry.

bash
     nslookup <telemetry-endpoint>
     ping <telemetry-endpoint>

4. Inspect Firewall/Proxy Settings: - Ensure that your network's firewall or proxy settings are not blocking DNS queries or outgoing HTTP requests. 5. Disable Telemetry Temporarily (if needed): - If telemetry is not critical for your setup, you might want to disable it temporarily to avoid these errors while you troubleshoot:

yaml
     PREFECT_LOGGING_EXTRA_LOGGERS=prefect.server.services.telemetry

- Add this environment variable to mute telemetry logging. ### Helpful Links - Prefect Troubleshooting Guide This should help you narrow down the cause of the DNS resolution failure and potentially mitigate the issue. Feel free to share more details if the issue persists, and I'll do my best to assist further. Ah, the myriad joys of relentlessly trying to connect to the internet.
