Use the download page for correct packages. See guides and FAQ for basics.
Checklist
Confirm app version and network type (Wi‑Fi vs cellular) before deep changes.
Try three servers in different regions first.
Settings that matter
After changing DNS, rules, or protocol, disconnect and reconnect.
Avoid stacking system proxy, browser proxy, and VPN global mode.
When to escalate
Account expiry and device limits need account fixes—not reinstall loops.
Compare builds on the download page.
Before you change advanced settings
Note the app version on the About screen and confirm your Proton VPN plan is active with free device slots.
Identify whether you are on home Wi‑Fi, corporate Wi‑Fi, or mobile data—blocks differ sharply by network type.
After a major OS upgrade, VPN extensions or profiles may be disabled until you approve them again in system settings.
Fast troubleshooting order
Try three servers in different regions (wait ~30s each), switch Auto to TCP, then test Global mode for 30 seconds.
If Global works but split routing fails, fix rules/DNS—not your password. See guides for routing notes.
Tether mobile data: if cellular works but office Wi‑Fi fails, focus on local network policy.
Use the download page and FAQ together
Package architecture and build numbers live on the download page—avoid random cloud repacks.
Billing, device limits, and common errors are summarized in FAQ; include version + server name in support tickets.
Streaming/gaming/corporate scenarios are indexed under guides—do not treat every issue as “cannot connect.”
Safety boundaries
Never type Proton VPN credentials into third-party web forms; unknown “config portals” can steal subscriptions.
Follow local laws; disconnect for banking apps that block proxies if required.
Shared accounts trigger anti-abuse locks that look like broken accounts—use your own plan.
When to stop troubleshooting
Stop when mobile hotspot works (local Wi‑Fi issue), TCP + new servers fix it, or renewing/unbinding devices resolves account errors.
Reinstall loops won't fix expired iOS profiles, MDM bans, or unpaid plans—classify the failure first.
If UI differs from this article, trust your installed build and compare with the download page.
