Could not start HTTP client

Error message

Could not start HTTP client

What it means

The remote server could not construct its Reqwest HTTP client while executing a run request — proxy settings or TLS backend initialization failed, so the server cannot perform outbound HTTP for that session.

Solutions

1. Check the proxy_url from settings is a valid URL
2. Verify TLS root certificates are available on the remote host
3. Retry client construction or degrade to no-proxy operation
