Access to JetBrains Account: Troubleshooting
If you encounter problems when attempting to log in to your JetBrains Account, this may be due to one of the following reasons:
No free ports
CLion waits for a response about successful login from the JetBrains Account website. If there are no ports available, CLion will suggest logging in with an authorization token.
Unable to open JetBrains Account in your browser
When you click Log in to JetBrains Account, CLion redirects you to the JetBrains Account website. If your system browser doesn't start, use the Troubles emergency button. CLion will suggest logging in with an authorization token.
No access to JetBrains Account
The login process requires access to the JetBrains Account website. CLion automatically redirects you to the website or lets you log in with an authorization token. If both options don't work and, you cannot access the website, contact your system administrator. Otherwise, it will not be possible for you to log in and start using CLion.
Log in with an authorization token
An authorization token is a way to log in to your JetBrains Account if your system doesn't allow for redirection from the IDE directly, for example, due to your company's security policy. CLion recognizes when redirection to the JetBrains Account website is impossible. It enables you to copy a link to generate an authorization token manually.
Click Copy link and open the copied link in your browser.
Log in to your JetBrains Account to generate an authorization token. After that, copy the token, paste it to the IDE authorization token field and click Check token. Once you've successfully logged in, you can start using CLion.
