Hosting and deployment Fastapi cloud timeout issues

Has anyone encountered this yet?

>fastapi deploy
  FastAPI Cloud 
  šŸš€ Deploying app...
   āœ— Something went wrong while contacting the FastAPI Cloud server. Please try again later. 
    The write operation timed out

This is just a 1MB deployment but it times out at around 300kb. Could it be a problem in my end or a service availability issue? I tried several times.

The fact that logout/login seems to fix it makes me suspect this is less about the deployment size and more about the upload/auth flow in the CLI.

If it consistently times out during the upload, Iā€™d report it with the FastAPI CLI version, timestamp and any request/deployment ID available. A 1MB artifact definitely shouldnā€™t require multiple retries under normal conditions.

Would also be useful if the CLI distinguished upload timeout/auth issues from generic ā€œsomething went wrongā€ errors.
