Take my last Hamon
TL;DR
- Close JetBrains Toolbox
- Remove the folder at
Library/Application Support/JetBrains/Toolbox - Remove the Toolbox folder, and restart JetBrains Toolbox
JetBrains toolbox is a great tool to manage IDEs from JetBrains and Android Studio. It runs smoothly when everything is fine. However, I meet a issue that I can’t update my IDE on macOS. It always show a dialog said:’Cannot connect to server, information may be outdated. Check proxy settings’. It can’t update no matter how I click the try again button nor reinstall from scratch.

JetBrains Toolbox lose ability to update
How can we solve this issue? After I digging on the Internet, I found It is quite easy to fix this issue. But the first action is to close your JetBrains toolbox app.
After close the app, open Finder and open the Library folder. If you can’t find Library folder, you can hold option key and click Go option from the top menu, you will see the Library folder option.

or you can find Library folder on your Home folder (Show hidden files)
When Library folder opened, Find the Application Support folder. In this folder, you need to find a folder called JetBrains. Remove the Toolbox folder inside the JetBrains folder. After that, You can reopen JetBrains Toolbox. You’ll find that It shows a welcome screen but our IDE is still there. Most importantly, It start update the app automatically.
Cheers everybody. 🥂
