Android Question B4A-Bridge Problem on VPN

hello everyone,

small problem with B4A-Bridge.
If I use it in my network everything works properly and I have no connection problem, now I have to use it on a corporate VPN (Romania-Brazil) and it keeps disconnecting.

It connects and immediately disconnects, reconnects and disconnects and so on ad infinitum.

I use OpenVPN 2.6 in UDP, is there any modification I can do to make the connection remain stable?

Thank you

P.S
the connection it's stable
