The thing is, VPNs can sometimes interfere with network traffic, especially for apps like Multiplicity that need direct access to your local network. Mouse without Borders might bypass some of these issues because it’s designed differently, focusing only on mouse and keyboard sharing without the added complexity of screen sharing.
A possible workaround is using a proxy. Proxies can help maintain a stable connection by rerouting traffic through a specific path that avoids VPN-related issues. I’ve had good luck with this approach, and it might solve the connection problems you’re facing.
