WinSCP 5.15.5
The error happened when I tried to open a remote file from a session that had not been used for, let's say 2.5 hours. After the error, the messate "The Host is not communicating for more than 15 seconds. Stil waiting ….." was presented, the automatic reconnection worked, but still same error was presented.
After restart, operation returned to normal
