The only thing I found was same issue like in the first part of the video where the redirection of the port did not stick in the container nextcloud .
For letsencrypt this time I even had to change the container’s name probably a bug in the Docker services, so I changed from letsencrypt to lets-encrypt in container name I can get a certificate with docker logs -f lets-encrypt if I keep the original config.php and nextcloud subdomain.conf, I can login in next cloud locally at https://192.168.2.150:444
but unfortunately it is not working remotely or locally if I change those like in the second video
