MyCloudEX2Ultra remote access doesn't work, works only in local with http

Yes, I read it but found nothing to solve my problem.

It was working fine previously, but since 3 or 4 updates it doesn’t work anymore.

As it wasn’t working anymore I set up my rooter to have a specific port to rederect to 32400 of the server.

I tried to restart it 2 times as somebody asked me to do there: Secure connection not working after last update
