SMTP Error: Could not connect to SMTP host

Hi!

Recently I have expirencing an issue while sending emails. If I tested manually, this plug-in shows this error at the top of the settings page “Email could no be sent”.

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

Full Debug:
