SSL handshake failure on Google Translate

Question

I have successfully been using the gTTS module in order to get audio from Google Translate for a while. I use it quite sparsely (I must have made 25 requests in total), and don't believe I could have hit any kind of limit that would cause my address to be blocked from using the service.

However, today, after trying to use it (I haven't used it in 1-2 months), I got the following program:

from gtts import gTTS

tts = gTTS('hallo', 'de')
tts.save('hallo.mp3')

To cause an error. I tracked down the problem, and I managed to see that even this simple program:

import requests
response = requests.get("https://translate.google.com/")

Causes the following error:

I would like to know if anyone has an idea what the issue could be. I can get on the Google Translate website without any problems from my browser, and have no issues using the audio either.

Answer 1

Accepted answer did not work for me since the code has changed, the way i got it to work was to add verify=False in gtts_token.py instead

response = requests.get("https://translate.google.com/", verify=False)

Answer 2

This looks like an error related to your proxy setting, especially if you are using your work PC. I have got the same issue, but different error message, for example:

gTTSError: Connection error during token calculation: HTTPSConnectionPool(host='translate.google.com', port=443): Max retries exceeded with url: / (Caused by SSLError(SSLError("bad handshake: Error([('SSL routines', 'ssl3_get_server_certificate', 'certificate verify failed')],)",),))

To further investigate the issue, you can debug it in the command line.

(base) c:\gtts-cli "sample text to debug" --debug --output test.mp3

you should see results as below;

ProxyError('Cannot connect to proxy.', OSError('Tunnel connection failed: 407 Proxy Authentication Required',)))

Solution: I have checked the gTTs documentation, there is no way to pass your proxy setting to the api. so the work around is ignore the ssl verification, which in not available also in gTTs. so the only way to do it is to change the following gtts files:

1. tts.py, in line 208 chage the request function to add verifiy=false

           r = requests.get(self.GOOGLE_TTS_URL,
                            params=payload,
                            headers=self.GOOGLE_TTS_HEADERS,
                            proxies=urllib.request.getproxies(),
                            verify=False)
   

2. file lang.py, line 56

page = requests.get(URL_BASE, verify=False)

Then, try again the debug command line. you should be able to get the file recorded now

(base) c:\gtts-cli "sample text to debug" --debug --output test.mp3

gtts.tts - DEBUG - status-0: 200
gtts.tts - DEBUG - part-0 written to <_io.BufferedWriter name=test.mp3'>
