SOLVED: jellyfin on Synology docker issues

[BadKarma]

Hello everyone, 
Yesterday I managed to port forward jellyfin hosted from my Synology NAS and everything worked. I followed exactly these guides:

https://mariushosting.com/synology-how-t...ver-https/
https://mariushosting.com/how-to-install...ology-nas/
https://mariushosting.com/synology-https...t-the-end/

Last night everything worked and I could access jellyifn through https both inside my network and outside from another location using the reverse proxy and certificates that I created on DSM. I used the default port 8096 for the local host and 8920 for the https port forwarding. 

This morning I tried to reconnect but it won't connect through the reverse proxy server link I created not through the local ip address of my Nass with the 8096 port specified. The Web browser shows two different messages, one says it cannot create a secure connection to the server and the other is that it cannot create a connection because the server is not responding

I am a bit of a noob at this so let me know if I can give you more information.
Thank you for everyone's help

UPDATE | SOLVED

I realized that my public domain IP provided by my ISP had changed in the middle of the night. I changed the external IP address in the DDNS setting to the new one and everything works, it was a very minor thing. For any other noob looking for answers, when setting up the DDNS make sure to set it as Auto so that it will automatically find the current external IP address
