Fix problems with Hangouts

If you can’t send messages, you may have Internet connection problems. Try these steps:

1. Check cellular data: Make sure data is turned on and that you have a strong signal.
2. Check Wi-Fi signal: If your signal is not working, turn Wi-Fi off and then back on.
3. Sign out of the Hangouts app and then sign back in: Learn how to sign out.

If you have server issues, you may see a red error . If you see this error, send your message again. If you still get the error after a few minutes, send the message again.

What happens when you get this error

• The message may not be stored in your message history.
• The message may not show on other devices.
• If your contact isn't online, they may not get your message when they sign back in.

Your computer is trying to connect to the server and you'll get your messages when you're connected to Hangouts again.

Fix the error

Make sure you're connected to the Internet and that these domains aren't blocked by your network administrator:

• *.client-channel.google.com
• clients4.google.com

If you have problems installing the Hangouts plugin, or receive a message asking you to reinstall it, check that your settings are correct.

If you use Chrome, you don't need the plugin. You only need the plugin if you use Firefox, Safari, Internet Explorer, or another browser.

1. Download and install the Hangouts plugin package again.
2. Make sure the plugin is enabled.
   • Firefox: Currently, some versions of Firefox can't be used to make video calls. To continue using video calls, download Firefox ESR. Learn more about why you need to download Firefox ESR.  To activate the plugin, click Menu  Add-ons  Plugins. Find the Hangouts plugin (Google Talk Plugin, or Google Talk Plugin Video Renderer).
   • Safari: Click Preferences  Security  Plug-in Settings. Find the Hangouts plugin (Google Talk Plugin, or Google Talk Plugin Video Renderer). Make sure the plugin is allowed.
   • Internet Explorer: Click Tools  Manage add-ons. Under "Show," click All add-ons. Find the Hangouts plugin (Google Talk Plugin, or Google Talk Plugin Video Renderer). Make sure the plugin is turned on.
3. If you use Internet Explorer, make sure you have the 32-bit version (not 64-bit).
4. If you use Windows 8, switch to desktop mode to allow the plugin to work.
5. Check your browser's extensions. Turn off any that use "click to run."

If you still have issues, try these steps:

1. Refresh the browser page.
2. Close or quit your browser, then reopen it.
3. Restart your computer.
4. Uninstall the Hangouts plugin, then download and install the Hangouts plugin again.
5. Try using the Chrome browser, which doesn't require the plugin. Learn more about Chrome.

When you message or talk with someone on Hangouts, your information is secured, including:

• Hangouts conversations and video calls in all devices.
• Meetings through Chromebox for Meetings.

Audio and video

• To improve audio and video quality, Hangouts calls use a direct peer-to-peer connection when possible, instead of routing through a server. Learn more about peer to peer connections.
• When you dial a phone number from a Hangout, audio is secured until it reaches the carrier network. Telephone carriers are responsible for the audio within carrier networks.

This can be caused if the computer is using incompatible video adapters or video drivers.

To fix it, upgrade the computer's video adapters and video drivers to the latest version.
