"Connection terminated before detection" in log reason for Unified Rulebase

[Arturxr]

we see in the accept logs the message Connection terminated before detection and at the same time it is visible in the reject logs to the same source, destination, port. However, we tried to telnet to the resource and port, which is supposedly dropped and we get access. It turns out that access is open and the connection is not reset, but we need to close it. What can we do about it?
