Avast Security Ultimate VPN Not Working – Stuck on "Searching for Fastest Location"

I am using Avast Security Ultimate, which includes a VPN subscription, but lately, the VPN has stopped working. It continuously displays "Searching for the fastest location" and eventually shuts off without connecting. I never had this issue before, and I’ve already tried uninstalling and reinstalling the app, but the problem persists. Is there a solution for this? I need this resolved as soon as possible, as the VPN is essential for my online security. I am awaiting a prompt response from Avast to address this malfunction and restore the VPN’s functionality.
