Briefly, this error occurs when Elasticsearch is configured to use Azure as a storage service, but the proxy host or port for Azure is not defined. This is necessary for Elasticsearch to communicate with Azure. To resolve this issue, you can either define the proxy host and port in the Elasticsearch configuration file or disable the use of a proxy if it’s not needed. Also, ensure that the defined proxy host and port are accessible and operational.

This guide will help you check for common problems that cause the log ” Azure Proxy type has been set but proxy host or port is not defined. ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: azure, repository-azure, repositories.
Overview
An Elasticsearch snapshot provides a backup mechanism that takes the current state and data in the cluster and saves it to a repository (read snapshot for more information). The backup process requires a repository to be created first. The repository needs to be registered using the _snapshot endpoint, and multiple repositories can be created per cluster. The following repository types are supported:
Repository types
| Repository type | Configuration type |
|---|---|
| Shared file system | Type: “fs” |
| S3 | Type : “s3” |
| HDFS | Type :“hdfs” |
| Azure | Type: “azure” |
| Google Cloud Storage | Type : “gcs” |
Examples
To register an “fs” repository:
PUT _snapshot/my_repo_01
{
"type": "fs",
"settings": {
"location": "/mnt/my_repo_dir"
}
}Notes and good things to know
- S3, HDFS, Azure and Google Cloud require a relevant plugin to be installed before it can be used for a snapshot.
- The setting, path.repo: /mnt/my_repo_dir needs to be added to elasticsearch.yml on all the nodes if you are planning to use the repo type of file system. Otherwise, it will fail.
- When using remote repositories, the network bandwidth and repository storage throughput should be high enough to complete the snapshot operations normally, otherwise you will end up with partial snapshots.
Log Context
Log “Azure Proxy type has been set but proxy host or port is not defined.” class name is AzureStorageSettings.java. We extracted the following from Elasticsearch source code for those seeking an in-depth context :
// Validate proxy settings
if (proxyType.equals(Proxy.Type.DIRECT) && ((proxyPort != 0) || Strings.hasText(proxyHost))) {
throw new SettingsException("Azure Proxy port or host have been set but proxy type is not defined.");
}
if ((proxyType.equals(Proxy.Type.DIRECT) == false) && ((proxyPort == 0) || Strings.isEmpty(proxyHost))) {
throw new SettingsException("Azure Proxy type has been set but proxy host or port is not defined.");
} if (proxyType.equals(Proxy.Type.DIRECT)) {
proxy = null;
} else {
