"install the suggested record" and connection problem

Hello everyone: It was in the "Email deliverability" option, because I needed to fix the SPF ("A SPF record does not exist for this domain"). So, as you can see, this option "install the suggested record" appeared to me, I clicked and thought it was going to be solved, but .. (see attach files) When I access my website, it doesn't even load! "This website cannot be accessed The server IP address of example.cl could not be found. Try running Windows Network Diagnostics. DNS_PROBE_FINISHED_NXDOMAIN" All this just by clicking on the button "install the suggested record". WTF. I'm noob. What I can do? What solution do you give me? PD: I can't speak english so good, so sorry.
