Hi Ana, You might check the Windows eventviewer for errors. If the standalone server crashes with an unhandled exception it should be logged there. Scott.

You need version 1.0.2 of the OpenSSL to be able to make the standalone/hyper_server setup to work in Linux: -rw-r----- 1 testapp unigui 2504576 Feb 13 22:33 libcrypto.so.1.0.2 -rw-r----- 1 testapp unigui 431232 Feb 13 22:32 libssl.so.1.0.2 Put this in the same directory as your standalone/hyper_server binary and make sure your binary has read access. My application (service) is run under the "testapp" account in this example. I used certbot to create free letsencrypt certificates and use apache (on port 80) as a validation server. sudo certbot certonly --apache -d mydomain.com -d www.mydomain.com Then setup the *.pem certificate files as described in the uniGUI manual. (/etc/letsencrypt/live/mydomain.com/*.pem) I use Debian 11 and Delphi 11.
