Problem with Cargo while installing pydantic-core

I've installed cargo and rust:

```bash
apk add rustc
apk add cargo
```

But every time I encounter the same problem when installing the pip package pydantic:

```bash

(venv) localhost:~/HamsterValor# pip install pydantic

if a proxy or similar is necessary `net.git-fetch-with-cli` may help here

```

I have no idea what to do. It would be very nice if someone could pay my attention to root of the problem or write a solution.

No repository file or test is named. Start by reproducing the shown `pip install pydantic` command and inspect the Cargo SSL failure while fetching crates.io; done means identifying whether the problem is in iSH or the environment and documenting a verified resolution.
