I created a server with Aternos with the software of forge and I installed the mod of Xaeros Minimap (and of course I installed forge) in the server and in my computer but when I try to enter to the server it gives me the error of "This server has mods that require forge to be installed on the client". I already checked that the mods and forge where the same version. Any ideas of what can it be? Sorry, english is not my first language
