my team is having an issue with the Send Email node.
We all tried the same configuration, but for some of us it’s not working giving this error:
"ERROR Send Email 3:1 Execute failed: Error while communicating with the smtp server: javax.mail.MessagingException: Can't send command to SMTP host;
nested exception is:
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"
Here some info about the node confguration:
SMTP host: smtp.gmail.com
SMTP port: 587
SMTP host needs auth checked
Username & password provided based on our credentials
Connection Security: STARTTLS
Connection Timout: 3000
We all activetad the “less secure app” from google, still, it works for some of us, while doesn’t for others.
I’ve asked everyone to uninstall and reinstall to the latest version (4.2.3) but it didn’t change anything.
are you all within same network? All running same OS? Have they checked they have imported certificate(s) successfully (there might be more than one needed)? If it works for some and not for others I would look for some pattern to try to figure out what configuration is missing…
