Huge packet loss during 6x6 battle

[YellowOrange21]

Huge packet loss during 6x6 battles on enemy or friendly bases ~25-30%
Packet loss persists even slightly after the battle and gradually decreases

In the past, this happened extremely rarely, but now it happens very often.

The attached photo (in the upper right corner - 12.5% with a further drop to normal values) shows how packet loss persists after the battle is over:

Since this happens often, it is very difficult to play when characters "teleport" and move very abruptly.

Does anyone else have this problem? Please reply.
I would like to understand whose fault this is, mine or the server's.
