docker hub had an incident on July 9. 2025 - that made publishing new versions to hub.docker.com failing.
This was at the time that the 1.4.8 version was scheduled to release, which delayed the release until July 10.
On a test server the update failed and user panel was not responding, docker logs -f openpanel shows: exec /usr/local/bin/gunicorn: exec format error
indicating that the downloaded image from docker hub is not complete.
Simply re-download it:
cd /root && docker compose down openpanel
docker compose pull openpanel && docker compose up -d openpanel
