PPTP Client does not work

Hi, I’m trying to connec to a mikrotik mtik rb532 LVL4 ver. 3.3, using either LVL4/5 rb433/rb750 as clients both ver 4.1 which is working fine since several years ago as PPTP server for windows clients , but If I try to use another mikrotik as client just it doesn’t terminate to connect

the only useful log I see is in the client is

LCP lowerdown
LCP down event in starting stage


many thanks
:smiley:
