Analysis

This sounds exactly like the issue: overleaf/docker-image#63
However, the thread had no other information about the fix but that it was working in version 0.6.1 of the container and the ticket was closed subsequently.

I know that time/date are sometimes an issue in Docker containers so I validated that time and date are correct inside the container (using date).
