LINE is a widely used communication tool in Taiwan, Japan, and Southeast Asia, making it an essential platform for businesses to connect with Asian customers. However, many users experience login issues after registering a LINE account. If you’ve ruled out common problems like network issues or firewall restrictions but still can’t log in, this guide provides step-by-step solutions for both computer and mobile users to regain access.
Solution to the problem of being unable to log in to LINE on PC
1. Check the version of LINE on PC
LINE officially announced that starting August 19, 2024, versions below 8.3.0 will no longer be supported. Additionally, macOS 10.15.7 and Windows 8.1 (and earlier) will also lose support. If you can’t log in, updating to the latest version from the official LINE website should resolve the issue.
2. Check whether the LINE mobile version has permissions enabled
Enable login permissions on mobile
Users who log in to the LINE PC version for the first time must first register a LINE account on their mobile phone or iPad, and then enable permissions on the mobile LINE before they can log in to the LINE PC version normally.
Click [Home] - Click [Settings ] in the upper right corner - Enter the settings and click [My Account ] - Turn on [Allow login from other devices].
3. Browser extensions
Many users have reported that when logging in to the LINE web version, they often see the message "Unable to log in at the moment, please try again later". In this case, you can try to log in using the LINE web version. (Note: The web version is only compatible with Google Chrome.)
(1) Open [Google Chrome] - Click the [three dots] in the upper right corner - [Extensions] - [Visit Chrome App Store].
(2) After entering the Chrome extension, search for [LINE] and click [LINE extension]. (If the search does not work, keep the English page untranslated and return to search several times until the separate LINE program appears.)
(3) Click [Add to Chrome] or [Add to Chrome] - Select [Add Extension] in the pop-up window.
(4) After the download is complete, click the extension icon in the upper right corner - click [LINE] - log in to your LINE account according to the pop-up window.
Possible reasons and solutions for failing to log in to LINE mobile app
1. Switch to different login methods
If you cannot log in using one method, you can try to switch to another login method to try to log in, provided that your LINE account is bound to other login methods.
2. Update your phone's LINE version
LINE announced that from November 2024, mobile versions below 12.18.0 will no longer be supported. If your app suddenly stops working, updating it via Google Play or the LINE official website should fix the issue.
Other solutions for LINE login issues
If the above methods cannot solve the problem of being unable to log in to LINE, it may be that the LINE account has been blocked. In this case, you cannot log in using the quick method. You can only appeal the account unblocking before you can use LINE normally.
1. Send an email to LINE for help
Go to the LINE feedback website, fill in the information as required, send it and wait for LINE to reply to the email.
2. Reach out to LINE customer support
Go to the LINE customer service website, use a LINE account that can be logged in normally to add customer service, and make an account appeal.
Frequently asked questions
Can I still receive messages if I cannot log in to LINE temporarily?
If your LINE account is not blocked, you can consider integrating your LINE account into SaleSmartly. Even if you are temporarily unable to log in to the LINE software due to the above reasons, you can still receive information from LINE customers on SaleSmartly to ensure that your business is not affected.
Can I log in to multiple accounts on the LINE PC version?
LINE doesn’t officially support multiple accounts on PC, but you can manage multiple accounts using third-party tools like SaleSmartly.
Why can't the other party receive the message I sent on LINE?
If the recipient isn’t intentionally blocking you, either your account or theirs may be restricted. Check both scenarios.
