Redownload jjsploit and if that doesnt work use krnl or comet

Redownload roblox and use the command "netsh winsock reset" on cmd prompt administrative power then try to join also i recommend you get krnl it gets way less errors hope this helped you

If you get that error wait a few hours and most likely it will work if not reinstall roblox and run command prompt in administratery then use the command "netsh winsock reset" and that should fix your problem

Wait a few hours and roblox fix's itself
