To be honest that was my initial thought as other clients using the same service but on different platforms are fine, so it’s a client/device specific interaction with HTX mode...which I’d bet HAProxy is more likely to be “compliant” than these particular Zero clients. I am happy to gather some additional traces though, to rule out some strange edge case however, but as you say, the initial requests seem fine so it’s questionable if traces will show anything useful. Do you think it’s worthwhile collection debug logs? > > -- > Christopher Faulet > -- Andrew Heberle
