[05:57:47 ERROR] [geyser]: Couldn't merge skin of .ActualSix095004 with head skin url https://textures.minecraft.net/texture/c52b1c8547e6e310291bfe9a7467bd21c0b6be6e93ddf64bf5a218441789ef5c j about geyser

This error is likely occurring as it took more than 5 seconds to retrieve the skin for a player.
See https://github.com/GeyserMC/Geyser/blob/master/core/src/main/java/org/geysermc/geyser/skin/FakeHeadProvider.java#L62 for reference - it waits for 5 seconds to get the skin, and throws if it can't get it - which is likely what's happening here.

What you could try would be increasing the cache-image setting to more than 0 - that would cache skins/other downloaded files for a while, which might reduce the amount of these errors.

sure but is there a recommend value for more than 0?

[onebeastchris]

Well, it's the amount of days it would be cached - try e.g. 1 or 2

ok i will try it to 2
