# Common issues
|
|
|
|
This page contains a list of common issues and workarounds.
|
|
|
|
|
|
## OpenSearch Dashboards fails to start
|
|
|
|
If you encounter the error `FATAL Error: Request Timeout after 30000ms` during startup, try running OpenSearch Dashboards on a more powerful machine. We recommend four CPU cores and 8 GB of RAM.
|
|
|
|
|
|
## Requests to OpenSearch Dashboards fail with "Request must contain a osd-xsrf header"
|
|
|
|
If you run legacy Kibana OSS scripts against OpenSearch Dashboards---for example, curl commands that import saved objects from a file---they might fail with the following error:
|
|
|
|
```json
|
|
{"status": 400, "body": "Request must contain a osd-xsrf header."}
|
|
```
|
|
|
|
In this case, your scripts likely include the `"kbn-xsrf: true"` header. Switch it to the `osd-xsrf: true` header:
|
|
|
|
```
|
|
curl -XPOST -u 'admin:admin' 'https://DASHBOARDS_ENDPOINT/api/saved_objects/_import' -H 'osd-xsrf:true' --form file=@export.ndjson
|
|
```
|
|
|
|
|
|
## Multi-tenancy issues in OpenSearch Dashboards
|
|
|
|
If you're testing multiple users in OpenSearch Dashboards and encounter unexpected changes in tenant, use Google Chrome in an Incognito window or Firefox in a Private window.
|
|
|
|
|
|
## Expired certificates
|
|
|
|
If your certificates have expired, you might receive the following error or something similar:
|
|
|
|
```
|
|
ERROR org.opensearch.security.ssl.transport.SecuritySSLNettyTransport - Exception during establishing a SSL connection: javax.net.ssl.SSLHandshakeException: PKIX path validation failed: java.security.cert.CertPathValidatorException: validity check failed
|
|
Caused by: java.security.cert.CertificateExpiredException: NotAfter: Thu Sep 16 11:27:55 PDT 2021
|
|
```
|
|
|
|
To check the expiration date for a certificate, run this command:
|
|
|
|
```bash
|
|
openssl x509 -enddate -noout -in <certificate>
|
|
```
|
|
|
|
|
|
## Encryption at rest
|
|
|
|
The operating system for each OpenSearch node handles encryption of data at rest. To enable encryption at rest in most Linux distributions, use the `cryptsetup` command:
|
|
|
|
```bash
|
|
cryptsetup luksFormat --key-file <key> <partition>
|
|
```
|
|
|
|
For full documentation about the command, see [cryptsetup(8) — Linux manual page](https://man7.org/linux/man-pages/man8/cryptsetup.8.html).

## Beats
|
|
|
|
If you encounter compatibility issues when attempting to connect Beats to OpenSearch, make sure you're using the Apache 2.0 distribution of Beats, not the default distribution, which uses a proprietary license.
|
|
|
|
Try this minimal output configuration for using Beats with the Security plugin:
|
|
|
|
```yml
|
|
output.elasticsearch:
|
|
hosts: ["localhost:9200"]
|
|
protocol: https
|
|
username: "admin"
|
|
password: "admin"
|
|
ssl.certificate_authorities:
|
|
- /full/path/to/root-ca.pem
|
|
ssl.certificate: "/full/path/to/client.pem"
|
|
ssl.key: "/full/path/to/client-key.pem"
|
|
```
|
|
|
|
Even if you use the OSS version, Beats might check for a proprietary plugin on the OpenSearch server and throw an error during startup. To disable the check, try adding these settings:
|
|
|
|
```yml
|
|
setup.ilm.enabled: false
|
|
setup.ilm.check_exists: false
|
|
```
|
|
|
|
|
|
## Logstash
|
|
|
|
If you have trouble connecting Logstash to OpenSearch, try this minimal output configuration, which works with the Security plugin:
|
|
|
|
```conf
|
|
output {
|
|
elasticsearch {
|
|
hosts => ["localhost:9200"]
|
|
index => "logstash-index-test"
|
|
user => "admin"
|
|
password => "admin"
|
|
ssl => true
|
|
cacert => "/full/path/to/root-ca.pem"
|
|
ilm_enabled => false
|
|
}
|
|
}
|
|
```
|

## Can't update by script when FLS, DLS, or field masking is active
|
|
|
|
The Security plugin blocks the update by script operation (`POST <index>/_update/<id>`) when field-level security, document-level security, or field masking are active. You can still update documents using the standard index operation (`PUT <index>/_doc/<id>`).
|
|
|
|
|
|
## Illegal reflective access operation in logs
|
|
|
|
This is a known issue with Performance Analyzer that shouldn't affect functionality.
