Istio ingress - 503 http errors when port 80 is marked as http2

Hi guys,

I’ve migrated merged our ingress resources to Istio gateways. Everything worked fine, but occasionally 503 http errors occurred. The message was saying that connection was reset before headers.

What helped to solve those 503s was changing name of port 80 to http instead of http2. Does anybody know if there is some issue regarding this? We have Istio 1.4.3 installed.

Thanks in advance. :slight_smile:
