Problems with the VPN and internet

Hello, I’m having a problem that I don’t understand: when using VPN, the red light of my wifi modem, which has the logo of a phone, turns red and flashes, and I’m 90% sure that the VPN has something to do with it. , but I don’t know exactly, thank you very much and I hope I can solve it

PS/pd: I’m translating this from google translate, I’m from Argentina where we speak Spanish.
