We use Elasticsearch 7.8.0. The problem we have is the “502 Bad Gateway” error that appears very often. The problem seems to occur between ms proxy and Kibana, but there is no information in the Kibana logs what could be wrong. If you need additional information, please let me know. I will be very grateful for any help.
What is ‘ms proxy’? Where do you see 502 error? How Kibana is connected to the Elasticsearch?
Kibana --> MS Proxy:9200 --> Elasticserch:9200
