gradio_client: 429 TooManyRequests on an AttributeError

[Pendrokar]

Describe the bug

When trying to connect to Gradio Spaces multiple times, I occasionally get the error AttributeError("'Client' object has no attribute 'src_prefixed'")

Connection errors out on the first try and then crashes as 'self.src_prefixed' was never set. https://github.com/gradio-app/gradio/blob/gradio%405.0.2/client/python/gradio_client/client.py#L866-L874

print(r) in that area of code gives the actual reason for failing to connect, which is: 429 Too Many Requests

Gradio 5 shows the wrong error at fault.

Reproduction

import os
from gradio_client import Client

client = Client("coqui/xtts", hf_token=os.getenv('HF_TOKEN'))
#occurs with and without token

result = client.predict(
        "Quick test.",	# str  in 'What should I say!? (max 512 characters).' Textbox component
        'en', #lang
        'https://cdn-uploads.huggingface.co/production/uploads/63d52e0c4e5642795617f668/V6-rMmI-P59DA4leWDIcK.wav', # voice sample
        None, # mic voice sample
        False, #use_mic
        False, #cleanup_reference
        False, #auto_detect
        True, #ToS
		fn_index=1
)

Run multiple times... at some point
