Premoves taking 0.4 seconds.

My internet is working perfectly fine. Gigabit fiber internet with 9ms latency. And no I'm not on VPN. Yet I'm losing 0.4 seconds per premove. I've lost a lot of games because of that lately. See screenshot of time used. I'm black in this particular game.

Premoves take a minimum of 0.1 second but can take longer if there's too much lag between you and the site live server

There are some things you can do to minimize issues.

Thank you but those did not help. As I said, my internet is extremely fast and no latency. I use wired connection. This only started happening in the last couple days. Before that premoves were consistently 0.1s

If your premoves are taking that long, then there is high lag, either from client side load, local network, or between you and the live server process.

I haven't seen other reports of higher than normal lag, so it could be regional in nature.

why do the premove do that

I have tried asking for help with terrible lag/ping issues as well. I have fast fiber, all other internet usage is super fast. Including other game sites. There surely must be loads of other players losing due this this? Love the site, would love to support but hard to justify paying when your losing due to poor servers.

Have high premove, ot 1 sec, why is this happening? My internet is working perfectly fine

Could be your client or a connection between you and the site. There was an issue earlier today, but I believe it was after you posted, and has been resolved. That shouldn't have caused issues with those in games already but may have.
