Problems on Self-Host

I’m trying to use the self-hosted version and trying to install it on my server which is not connect to the internet.
When i load images into my server and try"docker compose -p penpot -f docker-compose.yaml up -d", hosting is failed.
I check “docker logs penpot_penpot-frontend_1” , here’s the logs:
(opcmd)[root@zc-lanhu penpot]# docker logs penpot_penpot-frontend_1
