# What to check if Toky calls drop or they can't connect?

Toky works properly when it runs on Google Chrome or Mozilla Firefox browsers. When you use Toky in an outdated browser, connection problems can happen to inbound or outbound calls, which can lead to calls dropped or which can't connect.

To resolve this you must update your browser:

* If you use Google Chrome you can update it to its latest version by following[ this tutorial](https://support.google.com/chrome/answer/95414?co=GENIE.Platform%3DDesktop\&hl=en)
* If you use Mozilla Firefox you can update it to its latest version following [this tutorial](https://support.mozilla.org/en-US/kb/update-firefox-latest-version)

If Toky generates also messages for internet connection problems you can review [this article](https://tokyapp.zendesk.com/hc/en-us/articles/360020817998).

If after updating your browser and checking your internet connection, problems continue, contact our customer support team.
