500 error after Semaphore Installation

[FujiwaraChoki]

After installing semaphore and following the steps as outlined in here, I am unable to get past the log-in screen.

This is how the page looks like after logging in:

Any idea as to why this could be happening?

The issue is fixed. There turned out not to be enough vCPUs.

For anyone facing the same issue, as outlined in the documentation, you need at least 8 vCPUs and 16GB of RAM.
