Toggling Block List Drops Non-matching Active Connections

Proxyman version? (Ex. Proxyman 1.4.3)

Version 2.14.1 (21410)

macOS Version? (Ex. mac 10.14)

10.14.6 (18G6042)

Steps to reproduce

1. Stand up a server that can support long connections. To reproduce, we can just use netcat and never respond. In one terminal, run:

nc -l 9191

2. Establish a connection to the server in another terminal via Proxyman:

curl -x "http://localhost:9090" http://localhost:9191

3. Confirm the connection shows up in Proxyman as "ACTIVE".

4. In Proxyman, add and enable a Block List rule that does not match. For example:

ANY http://example/

5. The connection is killed and the client errors:

curl: (52) Empty reply from server

Expected behavior

Since http://localhost:9191 does not match the blocklist rule ANY http://example/, I would not expect that connection to be dropped. I am trying to block connections to a particular server, but it is dropping active connections to other non-matching servers too.
