I can't get the API to work with anything but IE on 64-bit Windows 10 Pro (1703).  I can use the following short PowerShell script to call CCMINER API just fine but not Z-Enemey 1.22.

$uri = 'http://127.0.0.1:4068/summary'
$Result = Invoke-WebRequest -Uri $uri

Powershell returns an error message after a long timeout period:

Invoke-WebRequest : The server committed a protocol violation. Section=ResponseStatusLine

Here is my miner command:
Miners\z-enemy.1-22-cuda10.0_x64\z-enemy.exe -a x16r -o stratum+tcp://us.ravenminer.com:4567 -u %RVN_WALLET_ADDRESS% -p %MINER_NAME% -b 0.0.0.0:4068 --api-remote --api-allow=0/0

I get "Connection Reset" in Firefox.  I get the same error message as reported above for Chrome (ERR_EMPTY_RESPONSE)

I've got a wireshark capture of the error but can't seem to figure out how to upload it.
