nginx error.log (ziemlich leer):
2022/12/13 16:51:22 [notice] 9106#9106: using inherited sockets from "6;7;"
Vielleicht noch eine Ergänzung. Ich habe Deine nginx config nicht 1zu1 übernommen, sondern den SSL Part ausgelassen, da ich noch einen Reverse Proxy (auch nginx) davor habe, der SSL macht. Listen Port ist also http/80.
