# Host Unable to Access Repository as Static IP Entry Present in Hosts File for the Domain

## Problem

Host blocked from accessing the S3 bucket for [*https://s3-us-west-1.amazonaws.com/platform9-neutron/el7/*](https://s3-us-west-1.amazonaws.com/platform9-neutron/el7/) to download the required packages.

## Environment

* Platform9 Managed OpenStack - All Versions
* Platform9 Managed Kubernetes - All Versions

## Cause

1. IP address 54.231.237.25 mapped to the Domain Name [s3-us-west-1.amazonaws.com](http://s3-us-west-1.amazonaws.com/) on the host was not reachable.

```

{% endtab %}
{% endtabs %}

## Resolution

The */etc/hosts* file on the host had set endpoints with static IP addresses which conflicted with DNS resolution. On removal of the entries, the host was able to successfully download the packages.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://platform9.com/kb/generic/solution/host-unable-to-access-repository-as-static-ip-entry-present-in.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
