Right now, the easiest way to activate JetBrains products is to use redirection of all requests from the application to localhost, but then nothing will work for you, neither pull/push git nor other plugins that use Internet access.
There is a better way, we will forward requests only to those that will go to the address account.jetbrains.com. This can be done without using the program, but it seems to me the easiest way to do it is through Proxifier. This program is available for both Windows and macOS.
