Anyone?

Have the same warning, no ideas what to do. GUI 1.1.6, Windows

It’s exactly what it says: there are old versions of the client running on the network. Nothing you can do about it… unless you want to drive over to their house, and help them upgrade their Chia software :rofl:

I don’t think they should log this as a WARNING personally…

That’s a whole lot of people who suddenly are using out of date software.

Maybe there are some bad local peers in your network neighborhood? I’m not sure.

I’m have this issue too, is there anyway to fix it?

Like codinghorror said, there is likely nothing that can be done. Chia software is rejecting software that is too far out of date. If people are not updating, you don’t know who hasn’t updated (well… you know who by IP but not physically who). Chia doesn’t have an automatic update system in place because they don’t have the resume of plotting thing figured out yet and automatic updates would kill plotting. For people who plot so many plots back to back and or parallel and or back to back + parallel or go headless, updating is not a priority.

The best Chia could do is remove this warning or change it to an INFO level notification. If and when I look at the logs, I ignore it.

Will there any effect on farming?
