Hello,
I have a Windows Server 2016 Essentials with SSTP VPN running. Clients (Win 10) can connect without any issues, browse folders, create files, copy files TO the server (any size) but they can't copy FROM the server. Not even files the client just copied to the
server.
Whilst trying to copy the files it shows the "calculating...". Eventually it stops trying with the following error:
Error 0x80070079: The semaphore timeout period has expired
I've tried OpenVPN, it has the same issues.
LAN does not encounter these issues.
When I RDP over VPN, I can copy files with it (both ways).
I've tried lowering the MTU on the VPN interface to no effect.
I'm lost for ideas and would love some help.
