Two days ago my django app which runs on an Ubuntu 18.04.2 LTS server with
apache and mod_wsgi in an venv with Python 3.6 throws an exception after
https login - as it seems - after a package upgrade.
To my understanding libssl/openssl is causing the error. The error message
below states that openssl_1_1_1 is not found. Though it seems to be
installed.
Could you guys give me a pointer? Please let me know if I need to provide
additional information.
Thanks and cheers!

Login Implementation
================
Im using djangos login views:
settings.py:
LOGIN_URL = '/accounts/login/'
urls.py:
path('accounts/', include('django.contrib.auth.urls')),
Error after Login Page of application / and django admin:
========================================
"Internal Server Error
The server encountered an internal error or misconfiguration and was unable
to complete your request."
Error in Apache Log
==============
[Thu Jun 13 18:58:10.555937 2019] [wsgi:error] [pid 1274:tid
140451378087680] [client 77.8.21.189:48212] mod_wsgi (pid=1274): Request
data read error when proxying data to daemon process: Connection reset by

response headers received from daemon process 'fotobau.ourdomain.de':
/srv/fotobau/djangoprojekt/wsgi.py, referer:
https://www.fotobau.ourdomain/accounts/login/
Unfortunately I failed to obtain a core dump till now.
Though right now I suspect the problem occurs when django tries to receive
the https/encrypted user and password. I suspect this because I got another
error message!
Another Error in Django Log
====================
Here I got a new error message: The first one ('Exception' is not JSON
serializable) is fairly common - though I didn´t manage to fix it till now,
it never really bothered.
Though after the package upgrade it raises a new error message (which will
raise itself again for 3 times) below - the one with "ImportError:
/usr/lib/x86_64-linux-gnu/libssl.so.1.1: version `OPENSSL_1_1_1":
