问题
I receive an error when i try to "redirect" and https request to http by a stunnel server.
construction:
flask server: serve https which includes an button with a https request to another server (stunnel4).
stunnel: receives the request and redirect it to a local (http) server.
the stunnel server failes by following error:
Mär 27 19:27:20 raspberrypi stunnel[1400]: LOG5[1744]: Service [https] accepted connection from <external_IP>:51874
Mär 27 19:27:20 raspberrypi stunnel[1400]: LOG5[1744]: s_connect: connected <local_IP>:7777
Mär 27 19:27:20 raspberrypi stunnel[1400]: LOG5[1744]: Service [https] connected remote server from <local_IP>:45444
Mär 27 19:27:20 raspberrypi stunnel[1400]: LOG3[1744]: SSL_connect: 1408F10B: error:1408F10B:SSL routines:ssl3_get_record:wrong version number
is it possible that this error caused by my manually (not officially certificatied) created SSL certificates?
flask server --> uses an manual created cert and key file. stunnel4 uses --> uses an manual created cert and key file (but different to flasks SSL files)
if you know any other methods to "redirect" the https to http, please comment.
