Stopped working

Hi,

I installed the plugin about a month ago, it was working fine for a few weeks…
Suddenly emails stopped coming and then I tested it from the plugin settings page and indeed it does not work.

Error message is:

Connection: opening to smtp.gmail.com:587, timeout=300, options=array

Connection: Failed to connect to server. Error number 2. “Error notice: stream_socket_client(): php_network_getaddresses: getaddrinfo failed: Name or service not known

Connection: Failed to connect to server. Error number 2. “Error notice: stream_socket_client(): unable to connect to smtp.gmail.com:587 (php_network_getaddresses: getaddrinfo failed: Name or service not known)

SMTP ERROR: Failed to connect to server: php_network_getaddresses: getaddrinfo failed: Name or service not known (0)

I’ve consulted G-Suite support (paid) and they’ve made sure all settings on that end are ok, then I checked with my hosting and as well everything seems fine.

When I turned off the plugin, emails are now sent again, but it’s still not good since emails are marked as spam (which is why the plugin is needed).

I saw this on another thread and wonder if it might be the issue:
“plugin should be able to send the mail via SMTP as long as wp_mail is being invoked.”
– Does this require a programmer changing wp code?
– Could it be the case even if the plugin did work for a good while

THANK YOU for your time !
🙂
