Have you always tried to run it on the same network? Might be something in your setup. I agree that it can sometimes be flaky, but usually adjusting the settings for the daemon solves the issue for me, either it's connected to too many peers (basically saturating all my available bandwidth) or too few. Looking around, some projects (like https://estuary.tech/ https://estuary.tech/) seems to have successfully stored around ~160 TiB of data on Filecoin (via IPFS), so there are setups where it does work successfully.
