Not sure if this is a bug in my network setup, or in WANOS, but with 1.4.1 (and 1.3.4), there seems to be a problem with certain sites not working properly.
The lead identified sites are
www.alibaba.com and
www.aliexpress.com.
When trying to access them, all I get is a blank page with a 200 and a 304 http response.
DNS resolution seems to work okay.
The test machines moved to the 'non-wanos filtered' side can access those sites okay.
One one side of the network, WANOS is installed on a physical device, and the other site everything is within a VMWare ESXi environment divided into segments.
It feels like WANOS is mangling the traffic, but I don't know where to start identifying and debugging this, other than it works if WANOS isn't in the way of the traffic.
I've not managed to identify any other sites with this problem.
