user after login redirect to NON https?

Hello

I canīt found any solutiojn for this..

From my CWP panel, the users login are secured with http with each customer domain, for example :

https://customerdomain.com:2083

When the customer login from there, he get error (because after login the panel is redirecting with NO https://)
If we modify manually that in the browser uRL bar to https:// the user panel display perfect.

I need to redirect after login to https:// instead to http://

Any help?
Thanks
Fabian
