Cannot Access External Services

Problem: In a network environment with a proxy server, an application cannot access external services through a proxy connection.

Explanation: This may indicate the proxy connection or connection pool is not configured properly.

Solution:

Check the proxy connection pool and verify EnableHttpProxy is set to true.
In Server Configuration (User Options), verify the proxy server settings are included, for example:
```
-Dhttp.proxyPort=8080 -Dhttp.proxyHost=proxy
```
