Error: “You are offline! You need to enable sales and either launch the MarketApp client or enable the extension!”

This error means that Market.CSGO does not detect the running MarketApp application, an active browser extension, or the launched mobile application. To resolve the issue, follow these steps:

Fix for the Browser Extension:

  1. Log in to the Steam website in your browser.

  2. Click on the extension icon and select "Disable Extension," then enable it again by clicking "Enable Extension."

  3. Ensure that the status of Steam and Market.CSGO has changed to "Connected."

Fix for the MarketApp Application on Your Computer:

  1. Check for the latest version of the application and update it if necessary.

  2. If you are using proxies, make sure they are working correctly and not blocking the connection.

  3. In the application, go to the account settings section and check the box: "Automatically enable sales on Market.CSGO."

  4. Click the "Pause" button, then "Resume" to restart the process.

Fix for the MarketApp Application on Your Smartphone:

  1. Re-login to the application using your Steam account.

❗️ Please Note:

For proper operation, you should use either the browser extension, the mobile application, or the MarketApp Client one at a time. We do not recommend using more than one application simultaneously.
