Reemo FAQ

The Reemo's remote desktop runs best on a 10 Mbps connection but you can reemote on speeds as low as 2 Mbps.

The maximum used bandwidth can be changed on the fly during a remote session:

• Low - 2Mbps
• Low - 5Mbps
• Medium - 7Mbps (default)
• Medium - 10Mbps
• High - 20Mbps
• High - 40Mbps
• Ultra - 80Mbps
• Ultra - 200Mbps

As many as your bandwidth and hardware can support :)

Reemo requires the installation of the Windows ViGEm driver (https://github.com/ViGEm/ViGEmBus/releases) on your remote computer. Reemo 1.9.0.0 or higher is required in order to ensure compatibility with the Virtual Gamepad Emulation Bus driver.

After the driver is installed, start a new Reemo session, push a button or two on your controller, it should appear on your remote Computer. You can test that everything is working by visiting https://gamepad-tester.com

Reemo requires at least one monitor to be plugged in to capture your desktop. If you do not wish to have monitors or want to add more monitors to your Reemo enabled computer, you can buy some cheap HMDI or Display Port dongles that mimicks a monitor and plug them to your GPU.

For signalling, Reemo establishes a TCP connection on port 443 on one of our signal servers.

To establish a connection, Reemo service on your target computer uses a random UDP port ranging from 58200 to 58400.

To establish a connection, your browser might use any UDP port.

If you are behind a corporate firewall or your router does not allow UDP packets, you might be using our relay server (TURN) over TCP. Because TCP has its on congestion control, it might burst packets and performances might drop using Reemo. We recommend that you use Reemo over UDP to get the best performances during your remote sessions.

This may be cause by an old GPU driver not handling the dynamic bitrate adjustments by Reemo. Please ensure that your hardware drivers are up to date. If your driver is up to date, please ensure that your internet speed can handle this quality settings, Reemo congestion control algorithm might lower your bitrate in case of severe packet loss.

If you use virtual machines and duplicate their harddrives, be sure to remove the "_id" file from the Reemo folder to avoid conflicts between your computers and restart the Reemo service. The "_id" file must be unique in order for your computers to register correctly.

What are the different roles in Reemo ?

Relay mode usually happens when your device cannot establish a direct connection. This is often related to your network setup. Try disabling IPv6 on both your computer and router, as this often resolves the issue.

Does an administrator need a Reemo license?

No, an administrator does not need a license to simply manage the organization. However, if this administrator also wishes to use Reemo to connect to remote machines, they will need a license just like any other user. (See: Licensing)

One of my users gets an "Error 560" and cannot connect.

Error 560 is most often caused by a required security setting not being met. The most common case is that two-factor authentication (2FA) has been made mandatory for the organization, but the user has not yet set it up on their account. (See: Security Settings)

How can I make sure users only connect during working hours?

You can configure access schedules to define specific time windows during which users are allowed to access machines. If a user cannot connect, check that their access schedule is correctly configured. (See: Usage Schedules)

How can I disable copy-paste and enforce automatic logout after inactivity?

Both options are available in your organization’s security settings. There, you can disable clipboard sharing and configure a session timeout (auto-logout). (See: Security Settings)

How can I convert an “External User” into a “Managed User”?

It’s not possible to directly convert an account. The process is to first remove the external user (the user must do it themselves or request assistance from Reemo support), then you can re-invite them as a managed user.

One of my users (SSO) cannot log in.

When configuring SSO (SAML), always test it with a user who does not have the “Owner” role. The “Owner” account should not be bound to SSO to avoid being locked out of the organization during setup.

Which flows and URLs should I whitelist on my firewall?

Reemo requires specific HTTPS URLs and network flows to be allowed for optimal performance. You can find the complete network matrix and required URLs in our network documentation. (See: Network Guides and Network Matrix)

How can I improve performance (smoothness) and achieve higher resolutions than my physical display?

You can manage two things:

• Performance: in the Reemo toolbar, adjust the "Bandwidth/Quality" slider to prioritize smoothness or image quality. (See: Reemo Toolbar)
• Resolution: Install the Reemo "Virtual Monitor" driver on the remote machine. It allows you to create virtual displays and unlock higher resolutions than the physical screen. (See: Additional Drivers)

Are ultra-wide resolutions (like 5120x1440) supported?

Yes, if the remote operating system supports it. You can set it directly in the OS display settings. If you are using the Reemo Virtual Monitor, make sure it is up to date. (See: Additional Drivers)

I have 3 screens on my remote machine but only 2 locally. How do I choose which ones to display?

The Reemo “Virtual Monitor Driver” is the best solution. When used with “Hybrid Mode,” the physical remote displays are disabled during the session, and you can choose exactly how many virtual screens you want to use. (See: Additional Drivers)

I can see my remote Mac screen, but my mouse and keyboard don’t work.

This is a permissions issue on the remote Mac. Go to macOS “System Settings” and grant the required permissions (Accessibility and/or Screen Recording) to the Reemo agent. (See: Installation - macOS)

I have no sound during my remote session on macOS.

If you’re using macOS earlier than version 13 (Ventura), you need to install the “BlackHole” virtual audio driver on the remote Mac to enable audio capture. (See: Installation - macOS)

Is there an “USB Companion” app for macOS?

That’s correct, there isn’t. For now, we don’t have a “USB Companion” app for macOS.

My Windows computer shows a blue screen (BSOD) caused by “reemaudio.sys”.

This issue is caused by an outdated audio driver. Update to the latest “Reemo Audio Driver” and remove the old one via the Device Manager to resolve the issue.
