Troubleshooting LINE Web Login Issues

If you encounter issues logging into the LINE web version, here are common reasons and solutions:

1. QR Code Not Working (No reaction or can't scan)

Cause:

• LINE app not open
• camera blocked
• browser issue

Fix: 

• Open mobile LINE → Use QR Scanner (Tap [...] > Add Friends > QR Code).
• Ensure camera permissions are enabled for your browser.
• Refresh the page or try a different browser (Chrome/Edge/Firefox).
• Clear the browser cache and reload the page.

2. "Unsupported Region” Error

Cause:

• LINE Web version is currently only available in specific regions.
• LINE restricts access based on IP address/region.

Fix: 

• Try using a VPN connected to a supported region (e.g., Japan, Taiwan).
• If you are in Mainland China, LINE services are restricted, a VPN is necessary.
• Check if a corporate/school firewall is blocking access; try a different network.

3. “Login Failed” After Scanning

Cause:

• Account issues (e.g., frequent logins from different locations, blocking).
• Login restrictions are enabled in mobile LINE settings.
• The mobile phone has no internet connection or uses an outdated LINE version.

Fix: 

• On your phone, open LINE Settings > Account > Ensure "Allow PC Login" is enabled.
• Update your mobile LINE app to the latest version.
• Check your mobile phone's internet connection.

4. Browser/Extension Problems

Cause:

• Browser cache or extensions are interfering.
• Privacy extensions (AdBlock, Privacy Badger) block resources.

Fix:

• Clear browser cache and cookies.
• Try accessing LINE Web in an Incognito/Private browser window.
• Temporarily disable ad-blockers or privacy extensions.

Log in to LINE with multiple accounts

Nowadays, whether you are doing social platform traffic diversion or a global platform and a direct sales website, multi-account operation is a must. Especially for enterprises, one employee may manage multiple accounts or multiple employees may manage a batch of accounts at the same time. If you switch accounts frequently, it will not only be troublesome but also easily lead to account ban.

Although the LINE web version brings a lot of convenience to office workers, the limitation of only being able to query information within 2 weeks is not very friendly to enterprises. Because it often takes a period of time to negotiate with customers, 2 weeks obviously cannot meet the needs of enterprises, so a basic tool of social media software SaleSmartly is needed.

SaleSmartly offers powerful message aggregation. As an omnichannel customer communication platform, it provides a unified inbox, consolidating messages from all your channels (including multiple LINE accounts). This allows you to receive and respond to messages from all your business platforms in one place, significantly boosting response efficiency.

Summarize

If you want to use LINE on your computer, you can rely on the above two modes. Both the official and SaleSmartly have their own advantages. You can choose according to your business requirements. And both of the above methods require you to register an account on the LINE mobile app in advance. You must prepare your account before using the computer version.
