Closed Port Error

[h2562961224]

Describe the bug
We use e2b to run vite server by "pnpm dev".
At first, internet access worked, but when I changed the files(a lots of files), it crashed——"The sandbox xxx is running but
there's no service running on port 9527."
And when I used "curl localhost:9527" in the sandbox, it returned as I wished——which means my vite server worked as well——the problem may happen in sandbox itself

Here is the log of vite:

! The local project doesn't define a 'packageManager' field. Corepack will now add one referencing pnpm@10.15.0+sha512.486ebc259d3e999a4e8691ce03b5cac4a71cbeca39372a9b762cb500cfdf0873e2cb16abe3d951b1ee2cf012503f027b98b6584e4df22524e0c7450d9ec7aa7b.

E2B-3006 Closed Port Error

[jakubno]

Hey @h2562961224, from the logs it seems the Vite server restarted, which made it temporarily unavailable.

Yes, it has restarted. I can get a correct response by accessing it directly via curl, however, when I visit it through 9527-xxx.e2b.app, it prompts a 'Closed Port Error'.

I found that getHost doesn't make an API call; it simply concatenates the id, domain, and port to form the host. I suspect an intermediate proxy responsible for health checks might be causing this 'Closed Port Error'.
