We have one KSC (184.108.40.2061 and Patch b) located at the headquarter and some branch offices, which use distribution points to lower the traffic on the WAN connection. All the computers (KES 11.1/11.2 and KSWS 10.1.2.996) at headquarter get updates from KSC and also use KSC as KSN proxy, that works fine.
The computers (same versions) at branch offices use their onsite distribution point for updates (that works fine as well) and KSN proxy.
The KES11.1 and 11.2 computers use the distribution point as KSN Proxy without any problems, but KSWS10.1.2.996 servers at branch office permanently log the following messages (using different file namens -> the KSN functionality does not work):
Do you have an idea why this does not work? Is this a bug of 10.1.2.996 (I have no patches installed for this version since there are no Core Fixes released publically).
The statistics state that KSWS uses the distribution point on TCP port 13111 (win10_1809_ksp is the distribution point, SRVAPWDS01 is the KSC server):
A network trace (wireshark) shows that KSWS opens a connection to the distribution point on TCP port 13111 and send some traffic, so it should work?!
The agent policy looks like this:
