Cannot not connect to vpn tunnel after renewing certs

hi all, i’ve been running an openbalena 2.0.0 server for a couple years now,
recently the certificates of my openbalena server expired so i followed [VPN Certs seems to be expired - #10 by wolf_karl]

The api is now working ok and i can list apps and devices with no problem. Mi issue is with the vpn tunneling, I’ve been using proxytunnel to connect to devices but after re creating the certificates I get the following message from the vpn container every time i try to fordward a new connection.

Why is it trying to connect to 172.18.0.8? it looks like a docker local ip but there are no containers registered with such address.

I need help here, thanks in advance.
