# ModPacketFix<\/p>\n
\n
\n
\n
\n<\/p>\n
A plugin that fixes some of the too big\/too small packet errors that occur when connecting to a Vanilla server with a Forge client.<\/p>\n
## Please Note: Some fixes require the Forge user to reconnect to the server<\/p>\n
Link to my development Discord<\/p>\n

– Client version and type (Forge, Vanilla, etc.)
\n– Server version and type (Spigot, Paper, etc.)
\n– Velocity version and Ambassador version

## Dependencies<\/p>\n
### Required Dependencies<\/p>\n
– ProtocolLib – For Bukkit\/Spigot\/Paper servers<\/p>\n
## Fixes Implemented<\/p>\n
– Server sending a recipe book packet that is too big<\/p>\n
## Common Forge Client Errors<\/p>\n
### Too Many Channels
\n**Client error:**<\/p>\n
“`
\nInvalid payload REGISTER!
\n“`<\/p>\n
**Server error:**<\/p>\n
“`
\n[00:00:00 ERROR]: Couldn’t register custom payload
\njava.lang.IllegalStateException: Cannot register channel ‘modid:channel’. Too many channels registered!
\n“`<\/p>\n
**Fix:**<\/p>\n
Add `-Dpaper.disableChannelLimit=true` to the server’s startup arguments<\/p>\n
**Note:**<\/p>\n
Due to the amount of channels and mods at play, textures\/items may be mismatched on the client<\/p>\n","protected":false},"excerpt":{"rendered":"
