# Troubleshoot
|
||
|
|
|
||
|
|
This section contains a list of issues and workarounds.

## Java error during startup
|
||
|
|
|
||
|
|
You might see `[ERROR][c.a.o.s.s.t.OpenSearchSecuritySSLNettyTransport] [opensearch-node1] SSL Problem Insufficient buffer remaining for AEAD cipher fragment (2). Needs to be more than tag size (16)` when starting OpenSearch. This problem is a [known issue with Java](https://bugs.openjdk.java.net/browse/JDK-8221218) and doesn't affect the operation of the cluster.

|
## 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.
|
||
|
|
|
||
|
|
|
||
|
|
## Can't open OpenSearch Dashboards on Windows
|
||
|
|
|
||
|
|
OpenSearch Dashboards doesn't support Microsoft Edge and many versions of Internet Explorer. We recommend using Firefox or Chrome.
|
||
|
|
|
||
|
|
|
||
|
|
## 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](https://github.com/opensearch-project/performance-analyzer/issues/21) with Performance Analyzer that shouldn't affect functionality.
|
||
|

|
## 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.
