I can't install magento 1 because I have error:
"The URL "http://magedk.local/" is not accessible."
"Unable to read response, or response is empty"
Magento installing on docker.
Something DNS Lookup was failing. Our server support changed something, I don't know what, but it appears to have fixed it.
This was not a Magento application issue, it was a server issue.
Better to contact your hosting provider to get out from this error.
