Did you copy and paste a quote block from another post and then put your own words in? WHY?! Update Forge and remove Roots.

Where did you get Forge from? Because what you're running is not 1.5.1 (or 1.15.1, which I assume is what you meant)

1.4.0 is no longer supported on this forum due to its age. Please update to a modern version of Minecraft to receive support.

How did you install Forge?

Please provide debug.log

All of your mods are from illegal repost sites, delete them all, read up on the StopModReposts Project, (link in my signature below), and get all your mods from the proper place

Make sure the mods and configs are identical on the client and server

Where did you get Forge?

That's not the debug.log, and is this a server that you own we're talking about?

Provide debug.log from both the server and the client

Stop making new threads about the same issue. If you won't provide a screenshot of your launcher then provide debug.log

Where are you seeing this error?

What launcher are you using? Please provide a screenshot.

SF3 is a 1.10.2 pack, you tried to install it on 1.12.2 You also didn't install it correctly.

No version, because the PR hasn't been accepted yet

If it's a specific port that Hamachi opens, start Hamachi then set the port in server.properties before you start the server

No, you're unbanned now, I was just doing other things as well

It was around 4:24 PM EST

I banned you because you started flooding the chat with c’s, did you fall asleep on your keyboard or something?

1.8.9 is no longer supported on this forum due to its age. Please update to a modern version of Minecraft to receive support.
