// Note there are some important timeouts involved here:
|
|
// nginx has a default 60 sec proxy_read_timeout, this means the connection will be terminated if the server doesn't send anything within that time.
|
|
// Previously we lowered the ConnectionTimeout from 110s to 55s to remedy that, however all we should've done is set an appropriate KeepAlive.
|
|
// By default KeepAlive is 1/3rd of the DisconnectTimeout, which we set incredibly high 5 years ago, resulting in KeepAlive being 1 minute.
|
|
// So when adjusting these values in the future, please keep that all in mind.
