OTA updates only work when I use VPN via phone hotspot — anyone else?

Hi everyone,
I’m running into a strange but consistent issue with OTA updates on my EV. When the car is connected to my home Wi-Fi, updates either fail to download or stay stuck at 0–5%. But when I share mobile internet from my phone with VPN enabled, the update starts immediately and completes without problems. Without VPN on the hotspot — same issue again.
Curious if this is a known EV connectivity issue or just bad ISP behavior.
 
2022 Tesla Model 3, AT&T home internet, Texas, USA. Updates only download when I use my phone hotspot with VPN enabled.
 
I’ve only had intermittent download issues with my previous, 50 mbs provider in foul weather. Since upgrading to 150 MBs, their free cable modem, and mounting it about a meter higher, no problems.

With my previous system, a WiFi repeater nearer to parking spot helped.

I’ve had the same thing happen, and the trick for me was checking categories that actually update with active games instead of waiting for results to appear. I’ve been using xsbets.com lately because the layout makes it easy to see what’s live and what’s quiet, so I don’t waste time clicking around. It also helped me spot new games faster, even when there weren’t any winners listed yet.

I usually hop onto Mostbet Casino⭐️Best Slot Machines⭐️Roulette and Live as I really appreciate how their platform stays rock-solid and lag-free regardless of my connection.

This behavior clearly indicates that your internet service provider or home router settings are likely throttling or blocking the specific traffic directed toward the car manufacturer update servers. Using a vpn works because the encryption hides the nature of the data and the destination from your isp filters which often mistakenly flag large vehicle updates as suspicious or low priority activity. To resolve this permanently you should try changing the dns server addresses in your router settings to public options like those from google or cloudflare since this often fixes the issue of downloads getting stuck at zero percent.
