Customer is using configuration offline/remote master. They generate trojan and analyze data at offline master, remote master communicates with trojan. Now in V4.11 they generated trojan at offline master, made infection, but trojan doesnt communicate with remote master.

To make a test, they generated trojan at remote master  - then everything is ok.

It seems, that trojan communication keys, which were synchronized before, changed after upgrade.

Is it possible it happened? Shall we copy again communication keys from ./finspy_master/data/certs from offline to remote master? Or is something different in new version?

Best regards
