[settings] Hostname not used when inviting new user

[guillaumegarcia13]

Hi, When I invite new users in the open source 0.9.11 version which I self-host, I get the following

even though I set up the hostname in my settings

Am I missing something?

This issue is not showing in the cloud hosted version.

According to the code in https://github.com/service-bot/servicebot/blob/ba374803dd256a6c3dad6580ab9d53e78b637b24/api/users.js it should actually use the request header "Host", right?

Yet, it seems this header is actually OK on my side
