I have an old RPi2.
Installed it with Stretch and did your commands above.
And,.. it works. got TLS1.2 SSL but 1.3 did not work.
When i update SSL, it's does not work anymore, also 1.2 does not work anymore.
So there is the problem.
Thanks for your help!

Yes, i installed the packages you mentioned and did the compiling.
No errors.
I think the problem is with openssl on the raspberry.
So i need somehow re-install openssl.
Making certificate's went fine.
Your instructions were good!

I did it and got this in my log: [2021-05-01 | 09:34:20] scripts.lua: lua error in script 'etc_keyprint.lua': ././scripts/etc_keyprint.lua:20: module 'openssl' not found: no field package.preload['openssl'] no file './openssl.lua' no file '/usr/local/share/lua/5.1/openssl.lua' no file '/usr/local/sh...

Hehe i know..

Can you make the old DC++ v0.868 work via VPN?

via cron works slightly differently, I also ran into it in the past.
you just have to give another command, unfortunately I don't know what exactly, i forgot.
