How to use auth2.0, self._sslobj.do_handshake() OSError: [Errno 0] Error

[pgshow]

When I tried to use Gmail auth2.0 for yagmail.

import yagmail

yag = yagmail.SMTP("sgdailydata@gmail.com", oauth2_file="./gmail-app.json", port=465)

subject = 'This is obviously the subject'
body = 'This is obviously the body'

# yag.send(to="pgshow@gmail.com", subject=subject, contents=body)
yag.send(subject=subject)

When I use python3.7, the error is self._sslobj.do_handshake() OSError: [Errno 0] Error

When I use python3.8, the error becomes. ssl.SSLEOFError: EOF occurred in violation of protocol (_ssl.c:1131)

Understand, My VPN issue. It totally works on a cloud server.

Don't use a Proxy or VPN, use the script on aws cloud server, and it may work.

I am having issues with sending myself emails using yagmail with the use of the OAuth2 verification. Here’s the code snippet: def send_mail(): gmail = os.environ.get("GMAIL") gmail_pass = os.environ.get("GMAIL_PASS")

yag = yagmail.SMTP("[arifurrahman@nypl.org](mailto:arifurrahman@nypl.org)",oauth2_file="./oauth2_creds.json")
# contents = ['This is the body, and here is just text',
#             'You can find an audio file attached.', '/local/path/song.mp3']
yag.send(subject="Great success Wawa Wee Wa!”)

The function runs and obtains my credentials from my json file ; however when I paste in the link that it tells me to go to, after allowing the app to do its thing, I get a black screen saying localhost refused to connect. As stated in the console I just take the localhost url at the top which contains the code param needed to continue on with the script as :”http://localhost/?code=….a&scope=https://mail.google.com/“, and paste it in the console, and then get a massive error as such:

Pertaining to to some SSL certificate error which may because the localhost refused to connect, which I’m not entirely sure how to fix. I checked my console.cloud.google account to make sure the oauth2.0 client ids are for a desktop app. I made the internal for the user type, but that doesn’t as matter as much because I am pasting the link on the google account that has access. I checked with to see if that was an issue by using a different email, but it gave me a 403 error which is expected as that gmail is not in the org I set internally. I also kept the authorized app domain fields blank and just gave the app a name and user support email and developer contact info, which is the bare necessity to make Oauth consent screen work. I am also using

I realized how you can fix the SSL error and all you need is this line: ssl._create_default_https_context = ssl._create_unverified_context

and import ssl in the code. I hope this helps anyone for those using oauth2 with yagmail
