I cannot lease a floating license in Debian 9 / Debian Stretch

Symptom : Exostiv Dashboard installed under Debian Stretch / Debian 9 is unable to lease a floating license.
Reason: Debian Stretch is shipped with OpenSSl 1.1 but Qt – which is used for developing Exostiv Dashboard – is still based on OpenSSL 1.0.
To work around this issue, please proceed as follows:
You have to change this symlinks: in /usr/lib/x86_64-linux-gnu form: libcrypto.so -> libcrypto.so.1.1 libssl.so -> libssl.so.1.1
libcrypto.so -> libcrypto.so.1.0.2 libssl.so -> libssl.so.1.0.2
