@Energen I did try port forwarding port 80 to 180 and 443 to 1443. However, whenever I forward port 80 to 180, I was unable to load Unraid on my browser so as Nextcloud.
I attached the port of my docker and router as well for reference. I am not sure if I done it correctly. Also, I was under the impression that if we use DNS verification as shown by Ed (Spaceinvader) as port 80 is been blocked by ISP, do we still have to port forward in our router?
I also try using the Window Network Diagnose, I attached the error report below as well.
