@mizart79 said in activesync client connection proxy error:
version = “2.3.4
As you have said you just set this up, and your z-push version is 2.3.4 I suspect you have followed some old tutorial on how to install it, and you have downloaded z-push from there.
The latest z-push release is 2.6.2 which is years newer. You should be starting with that, and ideally installing it from standard packages to facilitate easy maintenance.
Do you know what version of the zimbra backend you have used? Again, I suspect it is years old.
You should get the latest release from Sourceforge - Release 70.
That said, zimbra is pretty clear in it’s error messages. It says the nginx proxy cannot reach the MTA serveer for those users. I am not sure why.
