When we try running the project, we may get the message “ssl.SSLError: [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1056)“.
Python is commonly used for web or software design, visual analytics, assessment, and key content. Because of its convenience, it is often used by non-programmers, like scientists or accountants, for a variety of common operations, including financial institutions.
The above is a basic mistake that every developer may encounter in this well-known software. So, what causes it, and how is it settled? Take time to read to the end for a great solution.
When Does The Issue “ssl.SSLError: [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1056)” Occur?
You are attempting to send an email using your script, but you keep getting error messages.
ssl.SSLError: [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1056)
Which Are The Best Approaches For The Error ”ssl.SSLError: [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1056)”
Solution 1: Use TLS over SMTP rather than SMTP SSL
The only thing that helps you solve the error ”ssl.SSLError: [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1056)” is using TLS over SMTP rather than SMTP SSL. And even the SSL port is 465, not 587, but when you use SSL, the email go to the junk folder. To send an email, enter your code.
You would better grasp the responses by using the simple instances below.
import smtplib, ssl
port = 587 # For starttls
smtp_server = "smtp.gmail.com"
sender_email = "[email protected]"
receiver_email = "[email protected]"
password = "your smtp email password"
message = """This Message is send from python script"""
context = ssl.create_default_context()
with smtplib.SMTP(smtp_server, port) as server:
server.ehlo() # Can be omitted
server.starttls(context=context)
server.ehlo() # Can be omitted
server.login(sender_email, password)
server.sendmail(sender_email, receiver_email, message)
Solution 2: Run the program in trace mode as well as report the results
If the problem is your entire traceback, you could also run the program in trace mode as well as report the results in this:
$ HTTPX_LOG_LEVEL=trace python program.py
Solution 3: Consider the following 163 mailbox configuration
In the case, this error mostly brought by the below two mail server connection errors (Although TLS is turned on):
smtplib.SMTP(self.host, self.port, timeout=300) [Use when TLS is turned off]
Or
smtplib.SMTP_SSL(self.host, self.port, timeout=300). [Applied when TLS is activated]
Consider the following 163 mailbox configuration:
host="smpt.163.com"
port="25" [do not use TLS]
Or
port="465" [utilize TLS]
