# Troubleshooting

## The PC does not show up on my phone

- Check that both devices are on the **same Wi-Fi network**. Guest networks, some mesh systems and many office networks isolate devices from each other.
- Make sure Windows Firewall allows AeroCast on **private networks**. If you pressed Cancel at the first prompt, run allow_firewall.bat from the AeroCast install folder as administrator, or allow AeroCast in **Windows Security, Firewall and network protection, Allow an app through firewall**.
- Make sure the network is set to **Private** in Windows (**Settings, Network and Internet, Properties**).
- Turn off a VPN on the PC to test. Some VPN adapters confuse which address AeroCast announces.

## Android or Windows senders cannot connect

- The status line at the top of AeroCast tells you when Wi-Fi is off or the Wireless Display feature is missing.
- See [Connect a Windows PC](/docs/connect-windows) to install the feature and to allow projecting to this PC.
- If a Windows sender stays on "Connecting", restart casting on the sender.

## No sound on iPhone mirroring

- Check **Settings, Video and Audio** in AeroCast and choose the sound output device.
- Make sure the iPhone is not muted for the app you are mirroring.

## Paid features are locked

- Open **Settings, Account and Plan** and sign in with the email you bought with.
- A plan stays on for up to seven days without internet. After that, connect once so AeroCast can renew it.
- Each licence works on two PCs. Remove an old PC from your [account](/account).

## Send a log

Open **Settings, Diagnostics**, export the log and attach it to an email to [support@getaerocast.com](mailto:support@getaerocast.com). The log holds network details of your own devices; it never contains the pictures from your screen.
