Help Launchbox android NAS (With Lan and VPN Tailscale)

[FMLB]

Hello i have a situation, would i like to get help/solution

I have my roms games stored in a nas, the nas have 2 ip adress (lan in home and with tailscale for remote acess)

The option to download and play the game who exists on launchbox android its perfect for me.

The problem for me is when im out of lan home, stay in another place, travel… etc (with diferent ip), i can't download and play the Game. Play the game is only possible when i have already donwloaded in the device.

My configuration is above:

NAS
IP1 (LAN at Home) xxx.xxx.xxx.xxx
IP2 (Tailscale) yyy.yyy.yyy.yyy

My device who has the problem, have android 10 running.

The IP2 works fine when i'm stay connect in home.

When im stay out, i can acess the nas manualy (out of launchbox android) with the ip2 with tailscale and works fine, my problem is how to identify the nas in launchbox and work well?

I tried this 2 situations above and dont work, when im :
1) Import the roms again (out of lan home), but don't localize the nas (says its sleep…), but i the device acess normaly the interface of nas (out of launchbox)

2) Tried to modify the file .xml (inside of LaunchBox/data/Platforms) manually insert the ip adress of the rom (IP2) changes and got the message (No saved network credentials were found).
This process will dispend a lot of time, cause need to edit manualy each rom adress on xml file, but i tried to see if works. But dont work. Were i can insert the credentials to run?

Have another form to this work?

I tried to find a topic/read similars, but i cant solve this.
