Describe your issue

Hello everyone, I’ve encountered a problem. After installing yunohost from the official iso image, I assigned it a 4-level domain name. On the keenetic router, I assigned a dynamic domain name and specified the host where yunohost was installed. When I accessed the domain name, it redirected me to the host’s IP address: https: localip/yunohost/admin. I did the same for other hosts, and everything worked without any issues.
