Trying to display a Link to the Ticket System with variables

Dear Zammad Community,

I’m trying to display a Link to my Ticket System at the end of the E-Mail Signatures.

For this I’m using the following:

#{config.http_type}://#{config.fqdn}

It displays the correct value but the link cuts off after the https://. The fqdn is not part of the link. This looks unprofessional.

Is it just not possible to display a link this way?

Thanks i advance.
