Proxifier automatically closing connection after a few seconds

[Blkxy]

Just recently, and seemingly without any system or program changes on my end, my proxifier has begun to close the SOCKS5 connections on any connection attempt, after 6 or 7 seconds. This has gone on across multiple computers. Anyone else dealing with this issue or have dealt with it and found a fix?

Have you tried running the check to ensure that the proxy is working correctly, username password is correct etc.
