Ping issue

For some reason, since yesterday my ping has been dropping to zero, which is impossible. Also, when I try to join a game, it gets stuck on the "Entering server" screen. I've already reset my router, left it off for 20 minutes, uninstalled and reinstalled the game, and deleted the files. It’s not related to Bloxtrap, extensions, or browsers, as I’ve tried multiple browsers, and tried using roblox app version, but the problem remains the same.
