Hiddify won’t connect? How to fix it

Recommended

iPhone, Android, Windows, macOS, Linux

If Hiddify stopped connecting or pages load slowly (especially on mobile internet), enabling fragmentation (TLS Tricks) and disabling MUX usually fixes it. Below are step-by-step solutions for Hiddify on Android, iPhone, Windows and macOS.

Enable fragmentation (TLS Tricks)

This setting "shreds" your traffic into tiny pieces, and the carrier's equipment simply can't recognize and block them in time. This is the main fix for mobile internet (MTS, Megafon, Tele2, Beeline).

Open Hiddify and go to the Settings tab.
Find the Advanced or Config Options section.
Find the Fragment or TLS Tricks option.
Enable it and set a value of 10-20 (or choose Default/SNI).
Reconnect the VPN.

Disable MUX (Multiplexing)

MUX combines several data streams into one. With newer protocols (Xray VLESS) this feature often conflicts and causes freezes and connection drops.

Go to Settings.
Find the MUX (Multiplexing) option.
Disable it completely (uncheck the box or move the toggle to off).

FAQ

Why won’t Hiddify connect on mobile data?

Carriers filter traffic. Enable fragmentation (TLS Tricks) in Hiddify settings — it splits traffic so the carrier’s equipment cannot recognize and block it.

What if Hiddify keeps dropping?

Disable MUX (multiplexing) in settings and check time synchronization on your device — the VLESS protocol is sensitive to accurate time.

Universal tips

If nothing helped

Airplane mode

The carrier may have temporarily put your IP in a "penalty box". Turn on Airplane mode for 10 seconds, then turn it off. Your phone will get a new IP and the limits will reset.
