Samba over openVPN issues

I am experiencing a problem after upgrade from openwrt to LEDE.
I am using SAMBA over openVPN and I am able to resolve hostnames properly(doing some research after the upgrade, because it stopped working too).
My default LEDE device ip is 192.168.1.1, and I can connect to smb using both this address or LEDE hostname.
But when I am, for example, in some friend's house, connecting to my vpn through his wifi, an ip conflict occurs, because 192.168.1.1 is also the ip of his router, and it responds prior to my LEDE device.
The alternative is to connect directly to the tun0 interface (10.8.0.1) as i was doing before, with openwrt. And it used to work.
Now I try to mount the smb over vpn to 10.8.0.1 and get the output "Unable to find suitable address", which is strange, since I can ping this address and connect to every other service ports like ssh and http. I thought it woud be the firewall but I imported the same old conf file from owrt.

Here are some nmap outputs:

What can be the problem? Any help would be apreciated, Thanks!
