Why Does a Website Return 502 Errors Only During Deployments?

A 502 during release usually means the proxy cannot get a healthy response from the new application process.

Checks to make

Compare proxy, application, and process-manager timestamps; check health checks, startup time, socket permissions, and worker overlap.

When to get help

A staged deployment and monitored rollback can reduce customer impact. Informatix Systems can assess the symptoms, evidence, and next steps. Contact Informatix Systems to discuss this issue.
