Using hot-proxy with https?

Hello
I have installed Shopware 6 on Mamp and set it up to use SSL (https). But when I try to use hot-proxy I get the error:

SSL received a record that exceeded the maximum permissible length.

Is it possible to tweak some settings to get it working? I have tried to change the port on Apache to 9998 (SSL), but I get the same error.
