Step 1 โ confirm the exit country. Read the country and the 'Gemini supported?' verdict from the detector on this page. If you resolve to mainland China or any region not on Google's official list, you failed the region gate; nothing else matters until you move the exit to a clearly supported region (US, Japan, Singapore, etc. โ defer to the official list).
Step 2 โ separate 'region unsupported' from 'IP too dirty.' If the country is on the list but Gemini still won't open, look at the purity/risk score and the datacenter verdict: a datacenter (IDC) exit, or one flagged by multiple sources as proxy/high-risk, is far more likely to stall at login or human verification. That's not a region problem, it's a reputation problem on this specific exit โ switching to a residential, native, low-risk exit in the same region usually clears it. This page aggregates multiple risk sources and lists each hit, so you can see exactly which source flagged the IP.
Step 3 โ align account country with exit region. This is the Gemini-specific closing move many services don't require: keep the region you use long-term consistent with the country your Google account is pegged to, and stay on one stable clean exit rather than hopping across countries daily. Step 4 โ if you're on AI Studio/API rather than the consumer app and hit 'free tier not available in your country,' don't write off the IP yet: once the exit country is confirmed as supported, enabling billing on the project often unlocks access โ a different logic from the consumer app entirely.
