fpool proxifier can be a pain, but it’s worth it for the control it gives you. One thing I’d suggest is checking your network settings. Sometimes, firewall rules or antivirus software can interfere with how fpool proxifier handles proxies.
Also, if you’re using Windows, try running it as admin. That fixed a bunch of random errors for me.
