Error messages and what they mean

Last updated: November 10, 2026

Simulations show a message when a call cannot start, ends early, or cannot be scored. Find your message below to see what it means and what to do. Many of these you can fix yourself in a minute.


A message about your microphone or camera

Your browser could not use the device. Nothing in the simulation needs changing.

Message

What to do

Microphone access was blocked. Allow microphone permissions in your browser settings to continue.

Allow your browser to use the microphone, then start the attempt again.

No microphone was available. Check that it is connected, that your computer's privacy settings let your browser use it, and that no other app is using it.

Plug in a microphone, then check that your computer's privacy settings let your browser use it.

We couldn't start your microphone. Close any other app that might be using it, then try again.

Close anything else holding the microphone, such as a video call left open in another window.

We couldn't access your default microphone. Please select a device to continue.

Choose a different microphone.

Camera access was blocked. Allow camera permissions in your browser settings to continue.

Allow your browser to use the camera, then start the attempt again.

No camera was available. Check that it is connected, that your computer's privacy settings let your browser use it, and that no other app is using it.

Plug in a camera, then check your computer's privacy settings.

We couldn't start your camera. Close any other app that might be using it, then try again.

Close anything else using the camera.

Your browser is waiting for you to allow your camera and microphone. Allow access in the browser prompt, then try again.

Answer the permission prompt in the browser, then try again.

We couldn't receive the video stream for this session.

Check your camera, then your network.

A message about your network

Something between you and Solidroad is blocking the call. A VPN or an office firewall is the usual cause, so a different network is the quickest way to tell.

Message

What to do

We can't reach the voice service from your network. If this keeps happening, ask your IT team.

Try a different network, such as a phone hotspot. If it keeps happening, reach out to your administrator.

We couldn't connect to the voice service. Check your network or firewall settings and try again.

Turn off your VPN and try again.

The voice service closed the call before your audio reached it. Check your network or firewall settings and try again.

Turn off your VPN and try again.

Your connection to the voice service dropped, so the call ended. Check your network, then start a new attempt.

Move to a steadier connection, then start a new attempt.

The call will not start

Starting the attempt again clears most of these. One of them means you have the simulation open twice.

Message

What to do

This attempt already has a call in flight

You have the simulation open somewhere else. Close the other tab, then start again.

This attempt is finished, so it cannot start a call

Start a new attempt. The last one has already ended.

This simulation now runs on a different channel, so open it again

Reload the page. The simulation changed while you had it open.

All voice sessions are currently busy. Please wait a moment and try again.

Wait a moment, then start the attempt again.

The call failed to start. Please try again.

Start the attempt again.

We couldn't set up the call. Please try again.

Start the attempt again.

Something went wrong with the call. Please try again.

Start the attempt again.

The call ended before you finished

A call cannot be picked up where it stopped, so each of these means a new attempt.

Message

What to do

The session reached its time limit and ended.

Nothing is wrong. The call ran for as long as this simulation allows.

This session is no longer available. Start a new attempt to continue.

Start a new attempt.

The voice service ended the call unexpectedly. Start a new attempt to continue.

Start a new attempt.

The conversation ended because of a voice service error. Please try again.

Start a new attempt. Nothing you did caused this.

The conversation ended because of an AI model error. Please try again.

Start a new attempt.

The conversation ended unexpectedly. Please try again.

Start a new attempt. Tell your administrator if it happens again.

Your attempt was not scored

Nothing is kept from an attempt that was not scored, so take it again.

Message

What to do

We didn't detect any audio from you during the call. Check that your microphone is connected and unmuted, then try again.

Check that your microphone is unmuted and the right device is selected, then take the attempt again.

The call ended before we heard you, so it hasn't been scored. If you were speaking, check that your microphone is connected and unmuted, then try again.

The call ended before anyone spoke. If you were speaking, check your microphone before you start again.

We stopped receiving what you said partway through this call, so it hasn't been scored. This was a problem on our side. Please try the attempt again.

Take the attempt again.

The AI never spoke during this call, so it hasn't been scored. This was a problem on our side. Please try the attempt again.

Take the attempt again.

The AI stopped responding during this call, so it hasn't been scored. This was a problem on our side. Please try the attempt again.

Take the attempt again.

A message that needs your administrator

You cannot fix any of these yourself. Send your administrator the message and the name of the simulation.

Message

What it means

This scenario's voice is misconfigured. An admin needs to fix the AI persona before this can run.

The persona used by the simulation has no voice set.

There's a problem with this simulation, so it can't start. Contact your administrator.

The simulation cannot start a call as it is built.

This simulation is too long to run, so its author needs to shorten it

The simulation is over the length limit.

If that doesn't work

Send your administrator the exact message, the name of the simulation, and roughly when it happened. A screenshot of the message helps.
