Please, share the link to the guide you followed if not what I linked.
Also please, run the second command I shared. Or maybe this way to disable the pager so the end of the logs will be visible
journalctl -e -u docker --no-pager
When you share the output, format it in markdown like
```
output here
```
Here is some help: https://forums.docker.com/t/how-to-format-your-forum-posts/127295#p-202628-dockerfiles-compose-files-logs-and-code-4
You can also try checking general system logs:
journalctl -e
Or also with disabling the pager if you want to share the output, but the pager helps to browse the output.
It is possible that you didn’t have enough resources and the daemon was killed. Or something stops it from time to time.
