OK, turns out that you only need this line after setting the host name:

WiFi.mode(WIFI_AP_STA);

To be clear, this is a piece of code from me, which I'm using and don't get the issue !
If you try this code and see that this fix your issue, this probably means doing WiFi.reconnect() AFTER wifi_station_set_hostname(HostName) is the way to fix it.

Ah ! Ok !
Glad you've find it !

Hello, that's correct. Try to reset your router , you'll will see "yourhostname"
