Hello,

I have this error message. If i relaunch the VM and start worker again it work again, but all the time, after a few hours i have this error message :

Hi @LOG17,

This could be due to the internet connection or the infura node itself. We'd need more informations to inpect the issue.

Hi @zied-guesmi I confirm this must be an internet connection problem since this VM is on a computer with a VPN ( purevpn ) and VM on another one is not and work fine all the time.

Is there a way for VM to connect directly to the internet without passing through the VPN software, for exemple with VM network configuration ( NAT / Bridge / etc.. ) ?
