Delay

[coder-matthew]

(ESP8266) I use one line connected to channel B and everything works properly but with a delay of about 5 seconds, I thought it might be because it displays everything in the console but I turned off this option and nothing, I tried to change the "start delay" on the website but it doesn't work it didn't work, I also changed the artnet buffer to a smaller one (10-600) but it didn't help
Does anyone have an idea what could be the problem and how to fix it?
