@Marvin I keep getting this error - 'RuntimeError: Failed to reach API at http://127.0.0.1:4200'. I have tried reinitializing prefect, restarting the server, restarting the db, practically everything I can think of but I cant seem to solve it.

The error you're encountering,
RuntimeError: Failed to reach API at <http://127.0.0.1:4200>
, suggests that there's an issue with connecting to the Prefect API. Here are some steps and considerations to help you troubleshoot this problem: 1. Check if the Prefect Server is Running: Ensure that the Prefect server is actually running. You can start it with the command:
Copy code
bash
   prefect server start
Verify that there are no errors during the startup process. 2. Verify Network Configuration: Make sure that there are no firewall rules or network configurations blocking access to
127.0.0.1:4200
. This is the default local address and port for the Prefect API. 3. Check Prefect Configuration: Ensure that your Prefect configuration is correct. Particularly, verify that the
PREFECT_API_URL
is set correctly. It should point to
<http://127.0.0.1:4200>
if you're running the server locally. 4. Database Connection: If you're using a separate database, ensure that it's running and accessible. Sometimes, the API might fail to start if the database connection is misconfigured or unavailable. 5. Prefect Version and Compatibility: Make sure your Prefect version is up-to-date and compatible with your current setup. Running
pip install --upgrade prefect
can help ensure you have the latest version. 6. Troubleshooting Resources: You might find additional troubleshooting tips in the Prefect Cloud Troubleshooting Guide. If these steps don't resolve the issue, you might want to check for any specific error logs that Prefect outputs when you attempt to start the server or connect to the API. These logs can provide more detailed information about what might be going wrong. If the problem persists, consider opening an issue on the Prefect GitHub repository with detailed logs and your configuration setup.

I have tried all of the above but still no progress. I am currently using prefect server and not prefect cloud. Also, when I try to create block on the prefect UI after running this 'prefect server start', I see know blocks for me to add my credentials to. This wasn't the case when I initially started using prefect, I don't know why all these issues are coming up now.
