anvil.server.RuntimeUnavailableError: Failed to launch server runtime

Whilst not ideal, I highly suggest you pay for a plan whilst it is under assessment

Hi, Feb 3, 2025 - facing the same issue on the free plan since this PM. Worked fine until my lunch break.

Hi, @grippe

Sorry about that. We’ve looked into this issue and it should now be fixed. Please, do let us know if you see any errors again!

Solved, thank you very much

Hello! The same problem again
anvil.server.RuntimeUnavailableError
Could you please fix it again

Apologies for the inconvenience, should now be working again!

Thank you!
But, unfortunately, can’t check. Had to switch to paid plan.

Hi all!

I was facing the issue and I resolved it through changing the python version.

Open your app, go to Settings > Python versions, then set it to Full Python 3 instead of Python 3.10 (beta)
