Cannot send email Dashboard Subscription

Hi - using metabase 1.41.6. self hosted. Back end is BigQuery. Email service is Google Workspace

trying to do Dashboard Subscription via email. When I set up up; no complaints. But when I try to "Send email now" after some 10 seconds or so I get "Sending failed"

What I know

  • using App specific password
  • As an admin, I get notifications of users signing up (so I know email works sometimes)
  • Test email works

Hi @dhk
If you are a Pro or Enterprise customer, then please use the support email.

It is likely not problems with the email, but the generation of the subscription visualizations.
Check Admin > Troubleshooting > Logs for more detailed errors.

You should upgrade to Java 11:

Long time passing, but we upgraded Metabase beyond the version we were using and everything was peachy as the keenest of peaches.
