When KuaiLian shows Connected, the browser and other apps load, yet one app or a few sites keep spinning, first narrow it to “one thing” rather than “no internet at all”: contrast whether per-app proxy/split rules include it, the app’s own login and region state, and whether the target site limits your current exit. Every app and page dead → connected but no internet; everything opens but crawls → slow speed / high latency. This page lists no “which services unlock” set and promises no “guaranteed working” node.
Someone had KuaiLian connected—video and web pages loaded fine—yet one shopping app kept spinning through three reconnects. They blamed an expired account and dug through the plan page. In the end, split settings showed that app had been manually dropped into the “direct” list; moving it back to “through VPN” and reconnecting once fixed it. The difference was not the node—it was whether that app went through the tunnel at all.
Every app and page fails, like a full outage → connected but no internet. Everything opens but is generally slow, buffering, high latency → slow speed / high latency. Want to systematically set what goes through VPN vs direct → split tunnel / bypass list. Wi-Fi OK, only mobile data fails → cellular / APN checks. This page only covers “works overall, one thing fails.”
One app/site vs full outage vs generally slow
- One app/site won’t open: Browser and most apps work; only one or a few apps/sites spin, error, or won’t load → this page (split/routing/app itself)
- Full outage: Shows Connected, but every page and app fails, like the device is offline → connected-no-internet guide
- Generally slow: Everything opens, just buffers, high latency, slow downloads → slow-speed guide
Run one split test: while the failing app spins, use the same device’s browser to open a plain page and a site that normally needs the VPN, and see if only the target fails. Only that one fails → stay here; all fail → connected-no-internet; all open but slow → slow-speed guide. Don’t mix the three in one pass.
Confirm it is “one thing,” not “everything”
Goal: scope the failure first—one app, a class of sites, or all outbound traffic—rather than rushing to swap nodes or reinstall.
- While it fails, use the same device’s browser to open a plain page and a VPN-needed page; confirm only the target fails
- Do the same action in a different app (e.g. another video/social app) to see if only the original one stalls
- Note the exact symptom: endless spinner, network error, loads but blank content, or a region-unavailable message
- Briefly turn the VPN off, open that app on the local network, and judge VPN routing vs an app-side problem
If the app fails even with the VPN off, the problem is mostly the app itself or the local network, not KuaiLian routing. When the installer and menus disagree, verify the current platform build on the download page.
Per-app proxy / split rules not applied
The most common cause of “works overall, one thing fails” is that split rules put the app on the wrong side: something that should go through the VPN is marked direct, or vice versa.
1. Which list is it in
In split / per-app settings, confirm the target app sits under “through VPN” or “direct/bypass”—labels follow your client.
2. Reconnect after changes
After editing the list, disconnect and reconnect once; some clients won’t re-apply routing without it.
3. Newly installed apps
Recently installed apps may fall outside the default proxy scope—add them manually or switch to global for a contrast.
4. Domain vs app rules
Some rules match by domain, others by app; an app with many domains may partly proxy and partly go direct.
For a systematic setup of what goes through VPN vs direct, see split tunnel / bypass list. This page only cares whether this app currently takes the right path—and invents no “this app definitely works.”
The app itself: login state, region, and cache
When routing is fine, the block is often inside the app: it may decide loading by account region, last login state, or local cache, not fully in sync with your KuaiLian exit.
- Login / session: Is the app still signed in, or asking to re-verify? Follow the prompt to log in again before reinstalling
- Region logic: Some apps use the account’s registration or payment region, not just IP; a node swap may not change that
- Cache / stale config: Clear that app’s cache or force-quit and reopen to rule out a local hang; don’t wipe account data blindly
- Time / certificates: A wrong device clock or certificate issue can block a single app; check system time first
These are app-side states KuaiLian cannot change, and no node is promised as “guaranteed working” for a given app. Go by that app’s actual prompt.
Sites won’t open: DNS, certificates, and target limits
If only a few sites fail in the browser while others work, focus on resolution and the target’s policy, not the whole tunnel.
- DNS resolution: If a site won’t resolve or resolves wrong, check for DNS/split conflicts first; deeper checks sit in the DNS-leak resolver-contrast guide
- Certificate / HTTPS errors: “Not trusted” or time errors are often system clock or local interception, not necessarily the VPN
- Target-site limits: Some sites restrict datacenter IPs or your current exit; a different exit may behave differently, but nothing is guaranteed to work
- Browser cache / extensions: Try another browser or a private window to rule out local cache and extensions
Switching exits is only a contrast method, not a promise of stable access to any site. Install and setup paths: guides hub.
Still off: split, no-internet, and slow-speed
- Want to plan apps through VPN vs direct → split tunnel / bypass list
- It turns into everything failing, like a full outage → connected but no internet
- Opens but is generally slow, buffering → slow speed / high latency
These contrasts only show whether this app/site took the right path and whether the current exit reaches it. They do not prove censorship resistance, streaming unlocks, or a “better country node.”
Still stuck: what to record for FAQ / download
If split and app-side checks still leave only one thing failing, gather these before FAQ or in-app support:
- Which app or which sites fail; whether other apps/pages work at the same time
- Exact symptom: spinner, error text, blank content, or region-unavailable message (screenshots OK; mask accounts)
- Whether that app sits under “through VPN” or “direct” in split rules, and if you changed it
- Whether it also fails with the VPN off on local network; platform, OS version, KuaiLian version
When menus disagree with old tutorials, verify the current platform package on the download page. Install paths: guides hub.
