I setup a MT with 3.10 and pptp server. I disabled ftp,telnet,ssh and by accident www in /IP SERVICES
After I logged out of winbox and tried to log in again I get (port 80) Server error.
If I pptp vpn into the MT and try to winbox to the vpn ip I get Web Server Not Running.
I can connect via browser to MT and login with webbox - but can’t do much there.
Using MAC WinBox should work. Press the “…” button in the WinBox start dialog.
It should discover the router (if connected to the same LAN). By clicking on the displayed MAC address you should be able to connect. Then re-activate what you need in “/ip service”…
