In the invite email I use the variable "$ConfirmUrl" but in the received email it generates a url like https://myservice.portal.azure-api.net and it doesn't work

Hello,

In the template email to invite user I use the parameter :

$ConfirmUrl

Then, the new user receives the email with the following url :

https://myservice.portal.azure-api.net/confirm-v2/identities/basic/invite?userid=myUser&identity=myUserEmail&ticketid=...&ticket=...

When the user clicks on the link :

1. there is a security alert from the brower and if I by-passe the alert
2. it returns an error page "Service Unavailable"

To me there are 2 problems :

1. it should work
2. the url should use the custom ___domain name instead of the technical one

Do you know how I can fix this?

Best regards.
