Auto configuration failed

I had to reinstall my Debian 9.5. After the installation Nextcloud-2.3.3-x86_64.AppImage aborts with the following message:

Hello Thomas

I faced the same issue on Debian Stretch.
First, check that if you have openssl installed
sudo apt install openssl
Then I managed to solv this error by creating the OPENSSL_CONF variable
export OPENSSL_CONF=/etc/ssl/

and launch Nextcloud Appimage

Hope this will solve it on your system.

Many thanks.

OpenSSL was installed; version 1.1.1~~pre9-1


export OPENSSL_CONF=/etc/ssl/

solved my problem.

It didn’t work with me :v
I am getting the same error using on a php:7.4-fpm docker container.
