The issue is caused by an outdated version of FLS used to obtain the ticket. If configuration is the same but connection still fails let product contact FLS through transparent proxy that allows product to receive response from the server and doesn't change passed data.Īttempt to obtain license from the server leads to the error License Server response has not passed data integrity check: Invalid signature format.
If FLS page is successfully opened, set up network configuration, used by the web browser, for the product. If ping is successful, try to access FLS page from the web browser installed on the machine with JetBrains product, which fails to obtain a license, by visiting FLS address used in the product. License Server response has not passed data integrity check: Validation failed because there is a proxy which changes certificate data between product and local FLS.
