Model: CCR1009-8G-1S-1S+
OS: RouterOS 7.8
Hi,
We have a CCR1009-8G-1S-1S+, which have an ovpn server, and, for some reason that we can’t figure out, sometimes the PPP interfaces became duplicated, causing the links to not working properly.

The last disconnect reason is “port error“.

For solving this, we restart the equipment, or delete the dinamic PPP interfaces.
Is there any known configuration that cause this problem, or some workaround that allows to avoid this kind of problem?
We never had this kind of issue with other routeros versions, and with other equipement runnning on older versions like 6.49.7.
Best regards,
Rui Gomes
