I'd suggest running
curl -4 repo.almalinux.org
to see if your server can resolve repo.almalinux.org without IPv6. If that curl command can resolve repo.almalinux.org, it indicates an IPv6 networking issue on the server. In that case, disabling IPv6 could help to allow the Elevate process to continue past stage 4:
How to Disable IPv6
If that curl -4 command also fails, I suggest swapping DNS resolvers as outlined in the article I linked earlier. If you continue to face issues with Elevate after trying these steps, I would recommend opening a ticket with our team so we could take a closer look with server access.
