Can't use internet at redhat

I didn't delete or reset anything, but after booting my computer today, suddenly the internet is not connecting from rhel8 within vmware.
It happens the same on both wired and wireless, and in the system monitor, net is shown as 0 KiB for both outgoing and incoming.
The error message that occurs is as shown in the picture.
What should I do?
Since there is a project I am working on here, I would like to restore it even with remote support.
