Thank you a lot.
I am a little proud on myself that I have figured that out myself, too.

{:error,
{:load_failed,
'Failed to load NIF library: \'Error relocating /app/_build/prod/lib/explorer/priv/native/libexplorer.so: (null): initial-exec TLS resolves to dynamic definition in /app/_build/prod/lib/explorer/priv/native/libexplorer.so\''}}
and the fly.io logs show:
