Hello,
Same with me and I have entered every conceivable config.
I have done test from test tab. This is when I change from smtp.domain.com to my actual smtp server given by my hosting.
SMTP ERROR: Failed to connect to server: php_network_getaddresses: getaddrinfo failed: Name or service not known (0)SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting
Spent a few days back and worth with hosting provider – they have it working, it also works from Thunderbird, webmail and just now I’ve tried that other very popular SMTP mailer for WordPress that I won’t mention. Worryingly that worked too.
I’ve always used this with gsuite email I was using this mailbox with my hosting provider.
Version 5.2.2 WordPress
Version 1.3.9.1 Of Your Plugin
Please let me know if I can provide further info that could be of use.
Many thanks for your time it’s valued.
