After deploying the F5-TTS project using source code, you may encounter some errors when calling the API. Common errors are listed below:

1. Error: Could not fetch config for http://127.0.0.1:7860/

Answer: Possible causes:

• F5-TTS is not started.
• Incorrect port.
• The port is occupied by another program. Generally, AI project interfaces are often implemented using Gradio, and the default port is 7860.
• share needs to be disabled. Use the startup command f5-tts_infer-gradio --api, and remove --share.
• Upgrade the gradio_client on the calling side to the latest version by executing pip install --upgrade gradio_client.

2. Error: {detail:not found}

Answer: Possible causes:

• The gradio_client version on the calling side is too old. Please update it: pip install --upgrade gradio_client.
• Incorrect port or the port belongs to another project.

3. Frequent occurrence of errors like this:

    raise ConnectTimeout(e, request=request)
requests.exceptions.ConnectTimeout: (MaxRetryError("HTTPSConnectionPool(host='huggingface.co', port=443): Max retries exceeded with url: /SWivid/F5-TTS/resolve/main/F5TTS_v1_Base/vocab.txt (Caused by ConnectTimeoutError(<urllib3.connection.HTTPSConnection object at 0x000002174796DF60>, 'Connection to huggingface.co timed out.
