What triggers "failed to launch VM: machines are disabled for this organization"?

[maphew]

What exactly is making this test project transition from a “free plan, experiment, see what works” into a “you are trying to use pro features”?

The most recent similar thread on this is failed to launch VM: machines are disabled for this organization, which says this error is related to not having a credit card linked to my account.

I’m confused about the current pricing structure – is there is no longer a free tier?

My dashboard says I’m on “Legacy Hobby plan - Great for side projects, test environments, or just learning how to use Fly.io. Run basic full-stack apps for free, and pay-as-you-go as your project grows.” [emphasis added]

I’m fine with there being features that require money, I just want to know where the dividing lines are. I have no idea how much or how little the things I’m contemplating might cost and I don’t want to link a credit card until I have a handle on that.

(edited to link to the fly-io branch in the repo, show most recent failure log, remove extraneous info, and collapse ‘string of replies’ into single edited post, as per Discourse suggestion.)

Solved, courtesy of Free tier is dead? thread. The wording of legacy hobby plan in my profile has not been brought up to date. There’s a minimum $5/mth charge.

or not? Fly.io Resource Pricing · Fly Docs says:

Legacy Hobby plan

If you were on the free Hobby plan at the time that the paid Hobby plan became the default for new organizations, your plan is now called the Legacy Hobby plan. Your costs stay the same as they were, with no monthly subscription fee, and no included usage beyond the free resource allowances.

If you change your plan, you won’t be able to return to the Legacy Hobby Plan.

Emphasis added. I’m confused again. What free allowances?
