Describe the bug
When I’m starting only one this loading in parallel – all is ok, when more than three (including) – I’m receiving 502 error:
The issue reproducing regularly, not one-time issue and not fixing by restarting containers (we’re using k8s: 2 pods of dash app, 2 Redis instances, 2 scalable pods of nginx-ingress).
