message: send_mail: SMTP connect() failed.


Hello, I failed to retrieve the password email, and I put the screenshot in the attachment. Take a hard look
Error tells about SMTP connection failing.
Checking with openssl s_client -connect smtp.exmail.qq.com:465, connection is properly established, certificate is valid.
From the server running self-service-password, can you connect to that SMTP?
If not, it may be some firewall blocking that traffic.
Otherwise, could be worth changing your configuration, setting smtp_debug = true, see what we can find in the logs then ...
Is this running from a Docker container? If not: installed from RPM, deb, or git directly? Which version are you running?
docker mage: tiredofit/self-service-password:5.1.2

Ths getaddrinfo error suggests that PHP can't resolve the IP address for this DNS name.
Check the DNS resolver configuration in your container (/etc/resolv.conf).

Is this your container?
100.100 addresses are part of the 100.64.0.0/10 range, which is private.
Can you resolve smtp.exmail.qq.com?
Thank you so much
