Repl.it SMTPLIB OSError: [Errno 99] Cannot assign requested address

I am trying to run simple emailsender.py script on repl.it to send an email.
It works without any problem when I try to run it on desktop PC, but on repl.it I am having an error message OSError: [Errno 99] Cannot assign requested address as detailed below.
The emailsender.py program looks like this:
import smtplib
def send_email(username: str, key: str):
reciever = username+"#theirmail.cz"
sender = "my_email#email.cz"
topic = "Autothorization bot"
# header
msg = "From: %s\r\nSubject: %s\r\nTo: %s\r\n\r\n" % (sender, topic, reciever)
# add message content
content = "Your key is: " + key
msg += content
server = smtplib.SMTP('smtp.seznam.cz')
server.login('my_email#email.cz', "my_email_password")
server.sendmail(sender, reciever, msg)
server.quit()
When I try to run the script via python on repl.it, I get this error message after some time:
>>> import emailsender
>>> emailsender.send_email("username", "test_message")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/runner/botpy/emailsender.py", line 24, in send_email
server = smtplib.SMTP('smtp.seznam.cz')

(code, msg) = self.connect(host, port)

return socket.create_connection((host, port), timeout,
File "/usr/lib/python3.8/socket.py", line 808, in create_connection
raise err
File "/usr/lib/python3.8/socket.py", line 796, in create_connection
sock.connect(sa)
OSError: [Errno 99] Cannot assign requested address
This .py script is a piece of larger discord.py bot that I am trying to host on repl.it, but this should not have any effect, because this script alone is running well individually on desktop PC.
I've tried my best to figure out the cause of this error, but with no success so far.

For reasons unknown to me, a small configuration of commands fixed it.
New part of the script for sending the email looks like this:
server = smtplib.SMTP('smtp.seznam.cz', 587)
server.starttls()
server.ehlo()
server.login('my_email#email.cz', "my_email_password")
server.sendmail(sender, reciever, msg)
server.quit()

I had the same error and
port=587 fixed the problem

Trying to send email through python and getting error with socket

This is my code
import smtplib
from datetime import datetime
print("Sending Mail")
with smtplib.SMTP('smpt.gmail.com', 587) as smtp:
smtp.ehlo()
smtp.starttls()
smtp.ehlo()
smtp.login('gmail', 'password')
print("Logged In")
subject = "Current Time: " + datetime.now.strftime("%d/%m/%Y %H:%M:%S")
smtp.sendmail('myemail#gmail.com', 'myemail#gmail.com', "hello")
print("Sent Email")
I'm trying to send an email through gmail using smtplib, this is the error I get:

I made sure less secure devices is checked on gmail but I haven't tried every solution on the internet because I'm new to python and this is my first time using smtp and I don't get a lot of them, I think this has something to do with socket because that's another popular python module from what I've read but I don't know much about it and I'm not sure, if anyone can simplify what is wrong and explain it to me like I'm a 5 year old, it would be greatly appreciated.

You're using an incorrect domain which is not being resolved by DNS servers.
smpt.gmail.com
should be:
smtp.gmail.com

Python Error SSL: ssl.SSLError: [SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:726)

i'm trying to get the SNI from a (IP, destport 443) with python 2.7.15 and i'm using the last version of OpenSSL and the ssl module.
Here there is my code:
import OpenSSL as OSsl #This two modules are imported for the only purpose of getting the SNI using function defined by us down here getSNI
import ssl
ip = "52.85.25.17"
dport = "443"
#With this function we get the Server Name Identification for the trasmissions with Secure Socket Layer identified by the port 443. We only care about the destinationIP and the destinationPort
def getSNI(ip, dport):
if dport != "443":
commonName = "Not SSL"
print commonName
else:
server_certificate = ssl.get_server_certificate((ip, dport))
x509 = OSsl.crypto.load_certificate(OSsl.crypto.FILETYPE_PEM, server_certificate) #x509 is referred to the standard used for PKI (Public Key Infrastructure) used in this case for ciphering our informations about certificate
#FILETYPE_PEM serializes data to a Base64-Encoded
#getting the informations about Certificate
certInfo = x509.get_subject()
commonName = certInfo.commonName
print (commonName)
return commonName
getSNI(ip,dport)
This works, but for the address specified (in the snippet of code i posted here) I get this error:
Traceback (most recent call last):
File "getSNI.py", line 31, in <module>

File "getSNI.py", line 17, in getSNI

self._sslobj.do_handshake()
ssl.SSLError: [SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:726)
I have all modules and packages upgraded, i read a lot of issues about this topic and i don't know how to solve this problem
Edit1: Executing whois I found that this IpAddress is connected to Amazon, so are there any particular issues about Amazon and SNI?

The point of SNI is that there could exists several domains which are resolved to concrete IP address. So, the IP you provided (52.85.25.17) is the one of such addresses. Server couldn't decide which domain's cert you are requesting, so it terminates the connection with error.
Appendix 1. Catching SSLError exceptions
You can catch ssl.SSLError this way:
try:
server_certificate = ssl.get_server_certificate((ip, dport))
...
except ssl.SSLError as e:
common_name = "Handshake Failed"

How i could to make SSl Connection server using username, password by python?

Hello I would ask if i could do connection to extract some data from Tool Server.
so i making this code but i need to modify it to open this tool with username and password and extract data from My tool server.
import socket
import ssl
HOST, PORT = '10.74.159.82', 31039
def handle(conn):
conn.write(b'GET / HTTP/1.1\n')
print(conn.recv() . decode())
def main():
sock = socket.socket(socket.AF_INET)
context = ssl.create_default_context(ssl.Purpose.SERVER_AUTH)
conn = context.wrap_socket(sock, server_hostname=HOST)
try:
conn.connect((HOST, PORT))
handle(conn)
finally:
conn.close()
if __name__ == '__main__':
main()

I'm Beginner so i need to learn and supporting

It's hard to see exactly, but it seems the server you're connecting to (on https://10.74.159.82:31039) is using a self-signed certificate (or its CA is, perhaps).
It's perhaps better to create or buy a proper (non-self-signed) certificate, but assuming this is a test server this is fine.
So with what you have, your best bet is to allow self-signed certs in your SSL Context (and also, not to check the hostname - that will probably fail too as you're using an IP address):
context = ssl.create_default_context()
context.check_hostname=False
context.verify_mode=ssl.CERT_NONE

Unable to send email using gmail server using python

I am trying to send email using python. I tried many solution on Stackoverflow but none worked.
my code is -
import smtplib
fromaddr = 'user_me#gmail.com'
toaddrs = 'user_you#gmail.com'
msg = 'msg text here'
username = 'user_me#gmail.com'
password = 'pwd'
server = smtplib.SMTP('smtp.gmail.com',587)
server.ehlo()
server.starttls()
server.ehlo()
server.login(username,password)
server.sendmail(fromaddr, toaddrs, msg)
server.quit()
Code remain stuck at line server = smtplib.SMTP('smtp.gmail.com',587)
Tried port 465 and get this error -

tried this - smtplib.SMTP_SSL('smtp.gmail.com',465) and got this error
raise SMTPException("STARTTLS extension not supported by server.")

removing server.ehlo() had no effect.
removing server.starttls() caused below error -
