MikroTik

I have an interesting problem with Mikrotik routerboard.

I try to enable PPTP server ON Mikrotik with ip pool and account (secret)
I pass gre and 1723 throught FW.
I set up Android and W10 for test client.
account have static IP for client.

1st connection work fine, disconnect, reconnect work sometimes as well.

..and the problem:

After same connect/disconnetcion I can't connect anymore to Mikrotik PPTP server.
After I disable PPTP server and reenable again (no other changes made) work again for one or max 2-3 connection/disconnection.

Syntomnse:
I check the 1723 port from ping.eu/portcheck. IS open.
Connect/disconnect.
I recheck the 1723 port from ping.eu/portcheck. IS closed now.

Anybody have same symptompse?
RouterOS 6.35.3, and the fllowing changelog not contains relavant pptp bugs.

Idea?

Same here with 3011@6.36.2!!

god, thought i was going crazy

it happens on every single "server"on /PPP; often in PPTP, but also in SSTP and L2TP

only thing that works is what you've suggested, i even create a scheduler to reset servers, but still. Tried changing ports on SSTP tunnels to a higher one but problem remains.

i cant downgrade since its a 3011 and updates after 6.36 are critical (portflapping)

any help would be greatly appreciated!!

Major update

digging around when i reset the pptp server, the sstp server goes down, same backwards

really odd
