IPv6 not falling back to IPv4 (aiohttp upstream issue - No Happy Eyeballs support)

[Diend2023]

When I tried to run 'edge tts -- text' Hello, world '-- write media hello. mp3', this error occurred. I believe this is my own reason, but I cannot solve it.

Traceback (most recent call last): File "/usr/local/lib/python3.10/site-packages/aiohttp/connector.py", line 980, in _wrap_create_connection return await self._loop.create_connection(*args, **kwargs) # type: ignore[return-value] # noqa File "/usr/local/lib/python3.10/asyncio/base_events.py", line 1070, in create_connection raise exceptions[0] File "/usr/local/lib/python3.10/asyncio/base_events.py", line 1054, in create_connection sock = await self._connect_sock( File "/usr/local/lib/python3.10/asyncio/base_events.py", line 963, in _connect_sock await self.sock_connect(sock, address) File "/usr/local/lib/python3.10/asyncio/selector_events.py", line 501, in sock_connect return await fut File "/usr/local/lib/python3.10/asyncio/selector_events.py", line 541, in _sock_connect_cb raise OSError(err, f'Connect call failed {address}') OSError: [Errno 113] Connect call failed ('2620:1ec:c11::237', 443, 0, 0)

The above exception was the direct cause of the following exception:

Are you connecting to a VPN with an "IPv6 killswitch"?

[Diend2023]

I once failed to configure VPN, but then I turned off all agents in the environment variable. I am not sure if I have completely cancelled my configuration

[rany2]

This seems like an IPv6 configuration issue on your end.

[rany2]

Indeed, it seems aiohttp does not support Happy Eyeballs: https://github.com/aio-libs/aiohttp/issues/4451

[Diend2023]

So should I try to turn off ipv6?

[rany2]

Could you try that and let me know?

[Diend2023]

yes,thank you for your help

[rany2]

Perfect, I will see if I could work around it. In the worst case I'll consider switching to another library.

[Diend2023]

This seems to be valid, but I have encountered a certificate issue again:

aiohttp.client_ exceptions.ClientConnectorCertificateError: Cannot connect to host speech.platform.bing.com:443 ssl:True [SSLCertVerificationError: (1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:997)')]

[rany2]

@wanqifa Someone is hijacking your SSL connection, are you using this at a workplace? Edit, can you run this:

curl -4vvvv https://speech.platform.bing.com
curl -6vvvv https://speech.platform.bing.com

[Diend2023]

The first one can run

[rany2]

@wanqifa I mean can you share the output?

[rany2]

@wanqifa Thank you, my understanding is that the SSL error only happens sometimes; right?

[Diend2023]

Since I started using edge-tts, this function has not been successful. But I can use it on another device

[xiaoqiuyinhetaotao]

I use vim /opt/python3/lib/python3.9/site-packages/edge_tts/communicate.py

26 from aiohttp import TCPConnector

305 async with aiohttp.ClientSession( 306 trust_env=True,connector=TCPConnector(ssl=False) 307 )

[Diend2023]

I use vim /opt/python3/lib/python3.9/site-packages/edge_tts/communicate.py

26 from aiohttp import TCPConnector

305 async with aiohttp.ClientSession( 306 trust_env=True,connector=TCPConnector(ssl=False) 307 )

I have tried this before, but it failed. I will try your method again

[Diend2023]

I use vim /opt/python3/lib/python3.9/site-packages/edge_tts/communicate.py

26 from aiohttp import TCPConnector

305 async with aiohttp.ClientSession( 306 trust_env=True,connector=TCPConnector(ssl=False) 307 )

This is useful, thank you very much ！！！！！！！！！！！！

[rany2]

I use vim /opt/python3/lib/python3.9/site-packages/edge_tts/communicate.py

26 from aiohttp import TCPConnector

305 async with aiohttp.ClientSession( 306 trust_env=True,connector=TCPConnector(ssl=False) 307 )

I'm going to implement this but why did you disable SSL verification?

[Diend2023]

Perhaps the SSL certificate validation error was caused by invalid certificates in certain systems or Python versions. I have found similar issues in the issues section of aiohttp before.

Should be resolved by https://github.com/rany2/edge-tts/commit/8f8a3342038a283917c39af11435adb729f4ce42
