"php_network_getaddresses: getaddrinfo failed: Name or service not known" when creating a new page
Hi everyone, please help anyone know about this error.
I been create a new page through admin panel in Magento2 and I didn't noticed there is already a page that with the same name(old page). After it generate, I know that the system gives the new page a new identify-id which is totally different than the old page. After that I am thinking just delete the new page and put new content to the old page. However, this error pops up and now I can't access the admin panel. Any page I open will have this error.
Please can someone help? I really want to get this fix and know why makes that happen.
