multiplayer worlds not working

me and my friend recently have been having an issue where when we try to host and play on tmodloader we get stuck at a screen that js says syncing mods we have tried restarting unloading mods and reloading making sure everything is up to date and have both viewed the integrity of our files for both tmodloader and terraria aswell have uninstalled and reinstalled we have tried making other worlds but they end up doing the same thing trying to host them
