Please, can sombody help? The error is the following. How can I fix it? httpx.ConnectError: This exception indicates that the library could not establish a TCP/IP connection to the specified server (for example, the hostname or IP was unavailable, the connection was blocked, or the server was not running). The error was raised during await transport.handle_async_request(request), so the failure occurred when the physical HTTP connection was being established. The whole proxying process (contextlib, map_httpcore_exceptions) serves to map fundamental errors to higher-level httpx-exceptions, making error interpretation easier for developers. Possible main causes: Incorrect or unavailable URL or endpoint (domain, IP, or port does not exist, typo). A firewall, network, or proxy is blocking the connection. The target server's service is not running. DNS problem. The server rejects the connection (e.g., rate limit, service is down).
