Floating License Server Help

License Server response has not passed data integrity check: Validation failed

Issue

Error caused by unexpectedly formatted data received in response to license request sent to Floating License Server. Attempt to obtain license from server leads to the error

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.

Data Integrity Check Issue

Solution

Check connection to license server:

  • Try running ping <server host>.

  • 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.

  • If FLS page is successfully opened setup network configuration, used by the web browser, for the product.

  • 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.
