SOLVED: RemoteCertificateNameMismatch

[Raúl Casado Piqueras]

I am running jellyfin in a docker container.

OS: Debian GNU/Linux bookworm 12.7 x86_64
Kernel: Linux 6.1.0-26-amd64
Docker: 20.10.24+dfsg1, build 297e128
nginx: 1.27.2

It is configured with /jellyfin url base.

I run nginx in a container for reversing proxy and managing let's encrypt cert bot.

There is a persistent error that doesn't allow update metada:

Code:

Any ideas for resolving this issue?

Thanks in advance.
