premise @Marvin my prefect server has a ssl certificate now and when i try to deploy from another machine i get this raise PrefectHTTPStatusError.from_httpx_error(exc) from exc.cause prefect.exceptions.PrefectHTTPStatusError: Client error '403 Forbidden' for url

It sounds like your setup is experiencing SSL certificate issues when trying to deploy from another machine. Here are a few things to try: 1. Proxy Configuration: When using SSL, the certificates need to be properly configured. Make sure that the

HTTPS_PROXY

and

SSL_CERT_FILE

environment variables are set in your execution environment. Details: https://docs.prefect.io/latest/cloud/connecting/ 2. Environment Config Check: Ensure that your Prefect Cloud API key, environment variables, and account login are configured correctly. You can review your environment configuration using the

prefect config view

CLI command. 3. Whitelisting URLs: Make sure that URLs such as

app.prefect.cloud

,

api.prefect.cloud

,

<http://auth.workos.com|auth.workos.com>

are whitelisted for outbound communication. If these steps do not resolve the issue, you may find more insight by exploring the Prefect Discourse as well: https://docs.prefect.io/latest/getting-started/installation/ For additional support, you can also check open issues in the Prefect GitHub repository, such as: - https://github.com/PrefectHQ/prefect/issues/6685 for potential discussions around similar errors. If you encounter persistent problems, consider opening a new issue with the Prefect community.

the SSL_CERT_FILE needs to be a windows system env variable?

To configure the

HTTPS_PROXY

environment variable, follow these steps: 1. Set the HTTPS_PROXY Environment Variable: You can set the environment variable in your shell based on your proxy server settings. Here are examples for different operating systems: - Linux/MacOS (Bash):

sh
     export HTTPS_PROXY=<https://your-proxy-server:port>
     export SSL_CERT_FILE=/path/to/your/certfile

- Windows (Command Prompt):

cmd
     set HTTPS_PROXY=<https://your-proxy-server:port>
     set SSL_CERT_FILE=C:\path\to\your\certfile

- Windows (PowerShell):

powershell
     $env:HTTPS_PROXY="<https://your-proxy-server:port>"
     $env:SSL_CERT_FILE="C:\path\to\your\certfile"

2. Check Configuration: Use the following command to verify your Prefect configuration:

sh
   prefect config view

3. Whitelisting URLs: Ensure to whitelist the following URLs for outbound communication in a secure environment: -

app.prefect.cloud

-

api.prefect.cloud

-

<http://auth.workos.com|auth.workos.com>

-

<http://api.github.com|api.github.com>

-

<http://github.com|github.com>

@Marvin for the HTTPS_PROXY does it need to have the /api endpoint or will something like https://prefect.domain.com work?

The

HTTPS_PROXY

environment variable should refer to the proxy server, not the specific API endpoint. So using something like

<https://prefect.domain.com>

(assuming that's your proxy server's address) will work. Here's how it should look:

sh
export HTTPS_PROXY=<https://prefect.domain.com>
export SSL_CERT_FILE=/path/to/your/certfile

This setup means all HTTPS requests from the Prefect client library will be routed through

<https://prefect.domain.com>

. For more details, you can use this link: https://docs.prefect.io/latest/cloud/connecting/ If you need further assistance, feel free to ask!

@Marvin raise PrefectHTTPStatusError.from_httpx_error(exc) from exc.cause prefect.exceptions.PrefectHTTPStatusError: Client error '403 Forbidden' for url i get this when trying to deply from another computer my PREFECT_API_URL is set to http://prefect.domain.com/api

A

403 Forbidden

error generally indicates that the client does not have permissions to access the requested resource. Here are some steps to troubleshoot and resolve this issue: 1. Correct API URL Configuration: Ensure that your

PREFECT_API_URL

is correctly set to your server's API endpoint. For a local setup, for example, it might look like:

PREFECT_API_URL="<http://127.0.0.1:4200/api>"

In your case, ensure it points to the correct domain and port, like

<http://prefect.domain.com/api>

. 2. Check Authentication: Make sure that you have the necessary API tokens or authentication configured for accessing the remote API. Authentication configurations might include API keys, OAuth tokens, etc. 3. SSL Certificates: Set the

SSL_CERT_FILE

environment variable if your server uses custom SSL certificates.

sh
   export SSL_CERT_FILE=/path/to/your/certfile

4. Resource Permissions: Ensure that the user account or token you are using has the correct permissions to access the resources. Sometimes 403 errors can be due to a lack of permissions for certain actions or endpoints. 5. Whitelisting Needed URLs: Make sure that all necessary URLs are whitelisted for outbound communication, such as: -

app.prefect.cloud

-

api.prefect.cloud

-

<http://auth.workos.com|auth.workos.com>

-

<http://api.github.com|api.github.com>

-

<http://github.com|github.com>

@Marvin i have IIS Authentication setup on a reverse proxy, how would i make sure the permissions are correct. my domain account has access using NTLM but when i run the deploy from a python terminal / powershell im not sure how it authenticates

Configuring NTLM authentication through IIS for a Prefect deployment can be a bit tricky. Here's how you can ensure the permissions are correct: 1. NTLM Setup and Environment Variables: Make sure your IIS setup properly handles NTLM authentication for the Prefect API endpoint. 2. Ensure NTLM Authentication in Python: Use the

requests-ntlm

library to handle NTLM authentication in your Prefect deployment script. You may need to update your Prefect deployment script to authenticate using NTLM. 3. Example Script with Requests-NTLM: Here's an example of how to set up NTLM authentication:

python
   import requests
   from requests_ntlm import HttpNtlmAuth

   session = requests.Session()
   session.auth = HttpNtlmAuth('DOMAIN\\your_username', 'your_password')

   # Example Prefect API call, replace with your actual deployment code
   response = session.get("<http://prefect.domain.com/api>")

   if response.status_code == 200:
       print("Successfully authenticated and accessed the API.")
   else:
       print(f"Failed with status code {response.status_code}")

4. Setting Environment Variables: Set the

PREFECT_API_URL

, proxy, and SSL certificate environment variables as needed:

sh
   export PREFECT_API_URL="<http://prefect.domain.com/api>"
   export HTTPS_PROXY="<http://proxy.server:port>"
   export SSL_CERT_FILE="/path/to/your/certfile"

5. Running the Script in Powershell or Python Terminal: Ensure that you have set the environment variables in your Powershell or Python terminal before running the deployment script. If the issue persists, it might be worth checking the IIS configuration to ensure there are no additional restrictions or misconfigurations. For further detailed guidance on IIS and NTLM settings, you might need to refer to the Microsoft documentation or consult your system administrator to ensure the settings are correct.

@Marvin what does this do PREFECT_API_DATABASE_ECHO

The environment variable

PREFECT_API_DATABASE_ECHO

is used to control whether the SQL statements issued by Prefect's API will be logged to the console. It is primarily used for debugging purposes. Here is a brief overview: - Default Setting:

False

- Usage: - When set to `True`: All SQL statements issued by the Prefect API will be printed to the console. This can be useful for debugging or understanding the interactions with the database. - When set to `False`: SQL statements will not be printed to the console, leading to cleaner logs. Example Configuration:

sh
export PREFECT_API_DATABASE_ECHO=True

For more detailed information, you can refer to the official Prefect documentation on database settings. If you have further questions or need additional assistance, feel free to ask!
