two things jump out to me, I usually find that I need “option accept-invalid-http-request” when load balancing Exchange with HAProxy. You can see here that for Exchange 2010 I suggested it with success:

> [@Exchange 2010 RPC over HTTPS](https://discourse.haproxy.org/t/exchange-2010-rpc-over-https/2401/5):

> By SSL Bridging I only mean re-encrypting on the trip to the real servers so adding ‘ssl verify none’ will make it SSL Bridging. I’m glad ‘option accept-invalid-http-request’ fixed your problem, HAproxy follows RFC’s and drops non standard HTTP traffic by default unless you tell it not to, you could have verfied this was happening by using the stats page and a socat command to see errors: echo "show errors" | socat unix-connect:/var/run/haproxy.stat stdio More info here: [https://makandracards…](https://makandracards.com/makandra/36727-get-haproxy-stats-informations-via-socat)

Obviously Microsoft have been getting better… However, I’d still double check you are not seeing “req” errors on your state page and that :  
`echo "show errors" | socat unix-connect:/var/run/haproxy.stat stdio`  
Shows no errors either.

I too often end up raising the client / server timeout’s which in the past(Again mostly Exch 2010) I’ve needed to raise up to 45 mins or more, it may be worth a try as a test if nothing else…
