Hi,

I am installing OpenProject docker on a server using the air-gapped procedure. I ran the following commands to load the docker image and to load the containers, I got the following errors. What can I do next?

gunzip openproject-12.tar.gz && docker load -i openproject-12.tar

docker-compose up -d

Errors after loading the containers...
