E-mail templates: Link to "Thank You page" is not working

Summary:

Hello,

we have been configuring some e-mail templates for our Get-Response- Campaigns and for some responses, we have selected the "Use Thank You Page" type and for some others, we have inserted an External URL.

However, when we perform the "Send test e-mail" action and we click on the responses as seen on the sent e-mail, the links are not working and the pages linked to them are not opening.

Which could be the reason for this?

Thank you,

Efstathios.
