After upgrade to 5.15 PPP server stopped working

Hello everyone,

I am having this weird issue after upgrading to 5.15 version of RouterOS.
The devices that have the issue currenty: 751UHD and 450GL

On both of them after I installed the latest version (both were running 5.13 prior to that update) I am no longer able to establish an PPP connection. SSTP or PPTP both fail with the same error message:

: terminating… - could not determine local IP address

If this is the pptp server, then it says pptp-0 but…

I haven’t changed anything in the config whatsoever and suddenly - no PPP server.

I found a thread on this forum which reffered to a PPPoE server and “assign an IPaddress to the default profile of the server”.
However this is a no go for me.
I have tried assinging the internal IP, the address pool - both to no success.

One weird coincidence I am noticing - the 2 routers that fail the connection are both using 192.168.88.0/24 as internal networks and the other 2 I have (750G) are using 192.168.10.0/24

Any ideas on that one?
I am really stuck here :frowning:

BUMP
