Stuck at "Waiting for Outline server to be healthy"

[MSAA2024]

Hi, I tried to run the following script to generate an access key (the script worked fine before) but this time it gets stuck at "Waiting for Outline server to be healthy".
I found similar tickets here but I couldn't find any resolution. I'm wondering if anyone can help me with fixing this issue?

ubuntu@ip-172-26-0-38:~$ sudo bash -c "$(wget -qO- https://raw.githubusercontent.com/Jigsaw-Code/outline-server/master/src/server_manager/install_scripts/install_server.sh
)"
