Problem

There is an exception is being thrown Connection refused: getsockopt while activating JetBrains IDE (IntelliJ IDEA, Rider, ReSharper and others) using the JetBrains account option in the IDE window or ERR_CONNECTION_REFUSED is shown in a browser itself

Solution

Check the following possible solutions:

• does the same problem exist when you use a different browser?
• try clearing the cookies and cache in your browser, then try again;
• Add FIrewall rule for *jetbrains.com domain
• Check local hosts file. It should not contain any records with jetbrains.com
• Open https://account.jetbrains.com/ in the browser on the affected machine. If works:
  • Allow the IDE to use the same connection parameters. It tries to reach the endpoint via 443 port
  • Configure a proxy for IDE (for ReSharper please take a look at the Web Proxy Settings web page)

If a network connection still cannot be established, activate IntelliJ IDEA using an offline activation code or contact JetBrains support team for help.
