Question

Any Apollo maintainers here Having issues behind ELB of occasional 502 errors this seems to be similar to the issue I encounted with graphql where the default framework keep alive timeout is set lower than what AWS ALB ELB uses causing connection reset issues when the timing is right This article explains the issue and fix <https shuheikagawa com blog 2019 04 25 keep alive timeout > Be sure to look at the updated part at the bottom setting ```server keepAliveTimeout = 61 1000 server headersTimeout = 65 1000 This should be bigger than `keepAliveTimeout + your server s expected response time````

I believe setting an env variable and if that variable exist apply it forgive me if my node js is bad ```if KEEPALIVE TIMEOUT in process env server keepAliveTimeout = process env KEEPALIVE TIMEOUT 1000 server headersTimeout = process env KEEPALIVE TIMEOUT + 5 1000 ```
