TLS communication between the Stigg Sidecar SDK and the Stigg Sidecar service has been deprecated in favor of a non-TLS connection.

TLS self-signed certificates will expire on January 26, 2026, so upgrading the Sidecar service image and SDK is strongly recommended. 

To do so, follow the below steps:

1. Upgrade the Sidecar service image to version 2.498.0 or later. The new non-TLS port is set using the GRPC_PORT environment variable (default: 80). 
2. Upgrade the Sidecar SDK to version 3.0.0 or later and send requests to the new non-TLS port (same as GRPC_PORT).
