Migration to unRAID with Nginx Proxy Manager

[Przemek 70]

Hello, I finally migrate to my new home server and unRAID installed. I setup everything and it works almost perfect. Now I try to migrate my domain to new Nginx Proxy Manager but don't know how to do that.
1. I stop NPM container on old debian (dietpi) server.
2. Then I copy letsencrypt and config folders from old installation and move to new one.
3. Start NPM in unraid.
4. Change IP in proxy host configuration.
I get error that certificate is already used. I don't want to change domain for Emby. Is there a simple way to fix that? Anyone have experience with that?
Regards.

Have you tried to request a new certificate ?

Edit Proxy host -> SSL -> click domain name -> Request a new SSL certificate.

I have not tried this my self, but guess that should work.

Yes, of course I try. I get internal error. I also try clean install npm on unRAID and only jellyseerr works with new domain.

Do You have unRAID on ports 80 and 443? Because I choose that ports during first unRAID setup and meybe that are my problem?
