Question

Trying to store text in MinIO storage I get this error:
```
incoming request
Error storing text in MinIO: UNABLE_TO_GET_ISSUER_CERT: unable to get issuer certificate
 path: "https://bucket.railway.internal:9000/audiobook-texts?location";

The request is made from another internal service, but it works when I use the public domain, what can i do?
