# Cortex API 2.16.1

**March 28, 2022**

## New features

### Support for egress proxy

The back-end servers now can access the load balancers installed in the Cortex clusters deployed within the Asia-Pacific (APAC) cloud provider. Previously, communication was prevented between some Cortex services within the same cluster that impacted the core functionality of some web apps. To mitigate this issue, we deployed an egress proxy service to APAC Cloud that can successfully route intra-cluster communication. For issue details, view the first possible cause (No. 1) in this APAC Cloud Help Center – Server Load Balancer – FAQ documentation: [Why am I unable to access an SLB instance?](https://www.alibabacloud.com/help/en/doc-detail/55206.htm#concept-wzy-kyc-xdb)
