Blocks are not broken with EFFICIENCY Enchantment

I showed the problem with the video

Please offer me a temporary solution because I need it

 

The first one seemed to break fine. Are you sure that's the cause of it? Also, what version are you using?

 

Blocks tend to come back from the dead when your server is lagging. Try to take steps to reduce lag (Change weather to clear, etc.) and see if that helps.

 

i use last commit here. This problem only efficiency enchantment is also happening

 

I tried it when the weather was off. I do not think it's a lag

 

Its not lagging.
Its the estimation of breaking speed, efficiency is supported client side, but not server-side, so it detects the breaking speed as hacks.

 

Its a duplicate of another thread.

 

How can i fix it? A very urgent error for my server.

 

There's an issue for it at github, its not implemented, but its going to be soon.
No way right now

 

OH. I am wondering why my hub server is always destroying by players. Now I know why....
