Change RC server address RC windows desktop app

Hi All,
we are using fine running RC server without problems. In the near future we will want to change RC server address like below example:
https://chat.olddomain.com into https://chat.newdomain.com.
Question is how to do it without end users work?

We have tried make alias:
https://chat.olddomain.com is alias for https://chat.newdomain.com with 301 nginx redirects. It`s working well for website clients, but is not working for RC windows desktop app clients. Do You have idea how to finish task smoothly?

Hi!

I believe that the best course of action is to do a DNS Alias, instead of nginx redirect.

The browser will follow the link ok, but the App is probably not able to do so.
