We have DirectAccess configured on a Windows 2012 R2 server. This is working well, but I am having problems trying to connect when I am at home. I suspect it has to do with my router or ISP. I can connect fine from lots of other locations.
I get the following error in the DirectAccess Client Connectivity Assistant:
The IPHTTPS interface is not operational, last error code is 0x274c
From my research, this error means:
“A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.”
If I use my mobile phone as a modem, then I can establish a connection, so that makes me suspect that the problem is happening somewhere between my laptop and the DirectAccess server. I don't have anything unusual configured on my router - no firewall enabled, no port mappings, pretty vanilla setup.
Any idea how I can troubleshoot this? I'm a novice at Netmon, but willing to learn.
