It was on the forum of minecraft.fr

And thank you for your attention.

I read somewhere after 1.8 only server need to get the mod but mybad I will try again.

My friend need to have mods install on his forge version? If it's only that sorry to waste your time.

I'll give all detail. I tried first time with 7 mods to connect to server (no problem to load them) but I get the message "failing to synchronize registry data from server, close connection" then I decided to remove mod from server (I think I removed 3). This time I didn't get error so I invite my friend but this time he got the message. So like the first time I removed mods and just let one. But he still get the error message.

Oh yes I know why it s because I try to let just one mod on the server. But the first time the server load Biome O'Plenty too. I will find the log with it.

How could I verify if there are install. Even if normally there are install because when I launch ther server with my .bat i can see there are 5 mods find in the server.

Hi, I'm looking for a solution I saw there were other topics with this subject but no solution. My problem is I want play with a friend on a modded server, this server is on my PC (I play in localhost) and when I try to connect I don t get trouble but when my friends try to connect he get this message: "failing to synchronize registry data from server, close connection" We already play together on a vanilla server who was host on my PC and there were no problem. If you want log from server debug.log latest.log
