The program works correctly on http1 and http2, but on http3 it returns a 400 Bad Request status, and the Host header is missing.

how can I add "passenger_set_header Host $host:$server_port;" for nginx directive by default in passenger 6 GLS, because this header should fix it

I don't quite follow, do you mean how do you use the passenger_set_header config option? if so here's the docs: https://www.phusionpassenger.com/docs/references/config_reference/nginx/#passenger_set_header

plesk panel doesn't allow any users to add host header so, it is posible to add host header in builtin mode
