Sync Not Working on WiFi After Update? Works on Mobile Data
It works on mobile data.
It fails on WiFi.
Nothing else changed.
Same app.
Same account.
But sync suddenly stops.
No updates.
No data loading.
Just stuck.
Then you turn off WiFi.
Everything syncs instantly.
This isn’t random.
WiFi is blocking the request.
The App Didn’t Break — WiFi Did
After the update, sync depends more strictly on network conditions.
The app may now:
- require stricter connections
- use different endpoints
- reject unstable responses
Some WiFi networks can’t handle this properly.
The app is fine.
The network changed the outcome.
Same App. Same Account. Only WiFi Breaks It
This is the key pattern.
- mobile data → works
- WiFi → fails
Nothing else changed.
So the issue is not:
- your account
- your data
- the app itself
It’s WiFi.
What WiFi Is Actually Doing
The request never completes.
- traffic filtering
- blocked ports
- router restrictions
- unstable handling
So sync never finishes.
The app keeps waiting.
Nothing updates.
Why Mobile Data Works
Mobile networks are simpler and less restrictive.
- fewer filters
- direct routing
- better compatibility
So sync completes instantly.
Why There’s No Error
The app can’t clearly detect this failure.
- no error message
- no warning
- just incomplete sync
So it looks like a sync bug — but it’s not.
How to Confirm This
- WiFi → sync fails
- mobile data → sync works instantly
- switching networks fixes it every time
If switching fixes it, WiFi is the cause.
What Actually Fixes It
Switch networks.
- use mobile data
- try another WiFi
- restart the router
Also check:
- VPN settings
- firewall rules
Stay on WiFi, and it won’t sync.
What You Should NOT Do
Do not reinstall the app.
Do not reset your account.
Because:
- your app is fine
- your data is safe
This is a network issue.
Final Answer
Your sync didn’t fail.
WiFi blocked it.
So when sync works on mobile data but not WiFi,
change the network — that’s the only fix.
