Quick check • NAT Type 3 / Type D • “Can’t join friends”

Is restrictive NAT the reason you can’t join friends?

Most gaming connectivity problems are either Strict NAT / CGNAT (PS5 NAT Type 3, Xbox Strict/Moderate NAT, Nintendo NAT Type D), which breaks party chat, invites and hosting, or non‑NAT issues (outages, Wi‑Fi quality, subscriptions). This page helps you figure out which one you have — before you buy anything.

Quick symptoms check (optional)

If you already see Strict NAT / NAT Type 3 / NAT Type D on your console, tick that and you’re basically done. Otherwise, pick what matches.

Symptom check result

Select symptoms and click “Score My Symptoms”.

If your main problem is “slow downloads” or “internet drops completely”, it’s usually not NAT — it’s Wi‑Fi/line quality/congestion. NAT problems usually look like: parties, invites, joining friends, or hosting.

What to do next

Recommendation

After Step 1 (and optionally Step 2), we’ll recommend either StrictNATFix or the common non‑NAT fixes.

If it’s NOT NAT, it’s usually one of these

Subscriptions & access

PS Plus / Game Pass, sign‑in issues, parental controls, bans.

Outages

PSN / Xbox Live or game server downtime can look like “connection failed”.

Wi‑Fi quality

Packet loss/jitter breaks voice and matchmaking. Ethernet helps a lot.

DNS

Try 1.1.1.1 or 8.8.8.8 and reboot console/router.
