How to Fix ‘Failed to Synchronize Registry Data From Server’ Error in Minecraft

The ‘Failed to Synchronize Registry Data From Server’ Error typically appears with modded servers. While your server may start up just fine, you may experience issues with actually joining the game. Generally, this means that you either have an incompatible mod in your list or there are corrupted files that cause conflict. Thankfully, there are several solutions you can try:

Update Your Mods

One of the most common causes of this error is outdated mods. For example, while you may run a 1.19 server, your mod may only be compatible with up to 1.18. To fix this, check the mod’s download page and check if there are any up-to-date versions you can redownload. While many popular mods are reasonably quick with updates, some may take a few weeks or months.

Furthermore, if you’re using a modded client, it may also be outdated. In this case, you’ll have to attempt to update your client to be compatible with your server. All of your mods must match the server’s version!

Get More Mods

While this sounds peculiar initially, it’s another common problem for complicated modpacks. Many mods require other, supported mods that add custom commands, biomes, monsters, and various backend features to function. If you don’t have these mods downloaded and enabled, they’ll be incompatible with the game, causing numerous errors. To fix this, be sure to follow the instructions on the mod’s download page and check to see if you require any additional mods.

Delete Specific Mods

While it’s difficult to pinpoint exactly what mods may cause server errors, it’s generally only a few that cause them. If you’re using a mod that you’ve never used or tested before, try deleting it and rejoining your server to see if it fixes the issue. If that doesn’t work, go down your list until you find the bad apple of the bunch. By doing this, you’ll know exactly which mod (or mods) are problematic and can avoid them in the future.

Uninstall and Reinstall Your Mods

One potential problem is that while updating your mods, some outdated or corrupted files may linger that break your game. To solve this, try clearing out your mods completely and manually redownloading them. While this is a bit of a lengthy process, it’ll simultaneously wipe your bad, outdated files with new, updated ones, knocking out two birds with one stone.

Using Different or No Mods

While this isn’t an ideal scenario if you’re looking forward to playing the game with mods, it is a last resort if you still want to enjoy your time without issues. Since this error typically arises from mods, clearing your mods altogether and playing with a vanilla client will usually eliminate the problem entirely. It’s also possible that some mods are too outdated to stay compatible with the game’s current update. However, if you still want a modded experience, you can try changing your mods around, swapping some out for others, to see which works best for you.
