how to use specific weburl for access to webadmininterface

[Metanormal]

Hej Ho *,
i got sftpGo very easily installed and can reach the webadmin interface via default: http://www.example.com:8080/web/admin/
Since i have multiple virtual domains running on the same server, i found out that http://www.otherdomain.com:8080/web/admin/ also works, what i did not want.

So now i want to restrict access for the webadmin interface to https-protocol, a specific domain and path and port:443, like:
https://www.example.com/sftpgo/

I found some configurations in the sftpgo.json and am quite sure, that this is the place to do it.
But what i have to enter at what places, i dont understand. I tried the following:
``
"httpd": {
"bindings": [
{
"port": 443,
"address": "www.example.com",
"enable_web_admin": true,
"enable_web_client": true,
"enable_rest_api": true,
"enabled_login_methods": 0,
"enable_https": true,
"certificate_file": "/etc/letsencrypt/live/www.example.com/fullchain.pem",
"certificate_key_file": "/etc/letsencrypt/live/www.example.com/privkey.pem",
"min_tls_version": 12,
"client_auth_type": 0,
"tls_cipher_suites": [],
"proxy_allowed": [],

Can you help me with the missing informations? Am i going in the right direction or is the whole idea wrong? Anything?
I did not find a documentation for the sftpgo.json file and its entries, maybe you have a link to it, if it exists?

I am using apache2 under ubuntu, achieving https with letsencrypt automation.

Thanx in advnace, i say 42, Martin

Did you try setting the httpd binding web_root to /sftpgo?
