Any suggestions what can be wrong

jerome_grenier_Hi,
The "To" header in the response is lacking a URI... Maybe that's the issue?
Hope this helps!
writemikeFor anyone else stuck on this, it ended up being bug ID534458 which causes the 200 OK to be ignored since the F5 can't parse the response due to the lack of whitespace in the response. You can see it in the example shown in Ignat's question. There is a EngHF for 11.6.0 HF6 if you need it.
