Local Blynk Server on Synology NAS

Hallo Blynk User ans Supporter,
I have installed a local Blynk Server on Raspberry-Pi-Zero-W and I get no connetion between Blynk App and Blynk Server. The Website on Github is offline since 2021-07-23: https://github.com/blynkkk/blynk-server

Now I will install a local Blynk Server on my Synology NAS. But I need a tutorial for installation.

Thank you for help.

Watch tutorials on youtube… there are plenty.
