PPTP - 619 Error

Hi all,

Opened a new office in another City, we have there 2 computers both are identical (clone), now I have to to make a VPN connection to the central office Mikrotik PPTP Server. I’ve entered on the first PC remotely, quickly entered the IP of my PPTP Server and that’s it all good, the connection was established. After about 5 minute I entered remotely on the second PC, did the same thing as in first case but no luck I get the 619 error. Can’t understand why, changed options did other things but no luck, but after about half an hour, surprise, finally I was connected. After that I wanted to connect to PPTP server on the fist connection to see if both of them can work and again surprise the first PC that in first instance connected without a issue doesn’t want to connect any more, can’t understand why. Both computers are behind a router Huawei HG8245. I’ve tried to set in the PPTP Profile limits Only one - NO. But it didn’t help.

Here is the log:

Need some help with this one, thank you.

619 is always a firewall blocking something. Either your firewall, the remote firewall, or a firewall/router at the ISP(s)
