jujiale opened a new issue, #8166:
URL: https://github.com/apache/apisix/issues/8166
### Description
hello:
we have two apisix env(such as A and B), when we use apisix to proxy grpc
service, A always OK, but in B, when you first time send a request. It returns
502, but the following request all returns 200. and I also found that when we
send a request in B, after a while，send request again, then the first request
always return 502, the following return 200. I am confused of such thing.
because A and B env apisix version and depends are same.
when 502 occurs. the following error occurs:
`
[error] 20620#20620: *327238 no connection data found for keepalive
http2 connection while sending request to upstream
`
I want to get some idea from you. what causes it and how to solve it.
hope yours. thanks.
