1475	SSL routines:ssl3_get_record:wrong version number)	alirezaimi@…		"Hi 
I having trouble with this error and i doubt that this error back to nginx or python what !

https://github.com/python-telegram-bot/python-telegram-bot/issues/989

when i was use webhook method with nginx reverse proxy ability with self-signed cert according to this article (https://github.com/python-telegram-bot/python-telegram-bot/wiki/Webhooks), i have this error :

$ tail -f /var/log/nginx/error.log
when run bot python script :
*1 SSL_do_handshake() failed (SSL: error:14:SSL routines:ssl3_get_record:wrong version number) while SSL handshaking to u, client: YYY.YYY.YYY.YYY, server: 192.168.100.250, request: ""POST /XXXXXXX:XXXXXXX-XXY HTTP/1.1"", upstream: ""https://127.0.0.1:5661/23:XXXXXXX:XXXXXXX-XXY"", host: ""XXX.XXX.XXX.XXX""

when not run python script :
2018/01/26 11:03:57 [error] 18426#18426: *3287 connect() failed (111: Connection ref) while connecting to upstream, client: YYY.YYY.YYY.YYY, server: 192.168.100.250 request: ""POST /XXXXXXX:XXXXXXX-XXY HTTP/1.1"", upstream:https://127.0.0.1:5661/XXXXXXX:XXXXXXX-XXY"", host: ""XXX.XXX.XXX.XXX""

this is my nginx configuration :

server { listen 8443 ssl; server_name 192.168.100.250; ssl_certificate /home/aaa/TelBot/cert.pem; ssl_certificate_key /home/aaa/TelBot/private.key; location /XXXXXXX:XXXXXXX-XXY { proxy_pass https://127.0.0.1:5661; } }

and i run my app with :
updater.start_webhook(listen='127.0.0.1', port=5661, url_path='/XXXXXXX:XXXXXXX-XXY')

when i use nginx as my reverse proxy server this error happened and when i do not use it and directly run script everything is fine !
