gateway504 GATEWAY_TIMEOUT

[haibinyao01]

My gateway service has a low frequency (5-10/min) of 504 GATEWAY_TIMEOUT, but my downstream service is not under pressure. This part of the request looks like it is blocked at the gateway without forwarding, and this phenomenon occurs in iOS devices. Why does this problem occur
