Cant Break blocks randomly?

Server Stats:

Randomly, blocks will not break no matter how many times tried. Happens in all worlds.
No errors in console ever, no tps drops, and can still place blocks. Some research told me it was client side lag, but i can see other players try to break blocks and the animation plays but nothing happens. Started 3 days ago, servers been out for about a week now, player’s ping is good (40-100).
Players have reported that if you leave the world and come back it will fix, but this isnt guaranteed.

Anyone else having this issue?
