Describe the bug
When I'm using mobile data, the YouTube autocomplete suggestions got an error when trying to find something. This does not affected when you're connected to the Wi-Fi network.

Frequency
Most of the times & always shows up the error whenever you typing on the search box (only using mobile data)

Steps to reproduce the bug

• Disconnect from Wi-Fi & only mobile data turned on
• Open PipePipe normally
• Tap the search icon
• Type something
• If you got the error when searching, you'll got the "Sorry, something went wrong" error on the bottom of your screen

Device (e.g. Pixel 9 Pro)
Xiaomi Redmi Note 4 running MIUI 11.0.4 (Android 7.0)

Additional context
Is this possibly Google ban my SIM provider IP address? Because I got 403 error before I sign in my YouTube account. I don't know if this also affected on the NewPipe forks (including this one too), but hopefully it'll fix soon ASAP.

Yeah it is very likely since I can't reproduce it on my devices. Another possibility is YouTube is doing a A/B test.
At this time its better waiting to see what it really is.

Do you still have the issue?

[ToddIndry37]

Do you still have the issue?

Yes, I still getting that error if only using mobile data for remote autocomplete suggestions from YouTube. I don't know if this was some "parse error" that only affected to mobile data like quite strange.

Just reproduced it, luckily with debugger attached. The response is:

I found this error is DNS specific. Try using a VPN.

Close since this is YouTube's issue.
