I failed to run a telegram bot in another environment, more or less the error as follows.
urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='api.telegram.org', port=443): Max retries exceeded with url (Caused by SSLError(SSLError(1, u'[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:618)'),))
But after adding the following script, my bot finally managed to run in that environment. Maybe someone has a case related to SSL certificate verification, hopefully the following script can help.
#!/bin/python import ssl try: _create_unverified_https_context = ssl._create_unverified_context except AttributeError: # Legacy Python that doesn't verify HTTPS certificates by default pass else: # Handle target environment that doesn't support HTTPS verification ssl._create_default_https_context = _create_unverified_https_context
