I got this message on my dashboard: There are 95 email jobs that failed. Check your app.yml and ensure that the mail server settings are correct. The site is an SMTP-less install on a discourse.diy domain. Sidekiq shows: Next Retry Retry Count Queue Job Arguments Error right now 0 default Jobs::CallDiscourseHub {} Jobs::HandledExceptionWrapper: Wrapped TypeError: Unsupported command argument type: TrueClass in 2 minutes 5 low Jobs::UserEmail {“type”=>“digest”,“user_id”=>2,“current_site_id”=>“default”} Jobs::HandledExceptionWrapper: Wrapped ArgumentError: :arguments expected to be an Array of individual string args in 3 minutes 7 low Jobs::UserEmail {“type”=>“digest”,“user_id”=>2,“current_site_id”=>“default”} Jobs::HandledExceptionWrapper: Wrapped ArgumentError: :arguments expected to be an Array of individual string args in 9 minutes 9 low Jobs::UserEmail {“type”=>“digest”,“user_id”=>2,“current_site_id”=>“default”} Jobs::HandledExceptionWrapper: Wrapped ArgumentError: :arguments expected to be an Array of individual string args in 12 minutes 12 low Jobs::UserEmail {“type”=>“digest”,“user_id”=>2,“current_site_id”=>“default”} Jobs::HandledExceptionWrapper: Wrapped ArgumentError: :arguments expected to be an Array of individual string args in 15 minutes 13 low Jobs::UserEmail {“type”=>“digest”,“user_id”=>2,“current_site_id”=>“default”} Jobs::HandledExceptionWrapper: Wrapped ArgumentError: :arguments expected to be an Array of individual string args … … … … … … The site is on 2026.1.0-latest (0caa6e34fe) Is it expected?

Thanks for posting! That email doesn’t work is expected, but the errors you are seeing are unusual. They might be due to something else in your setup. When I try to send an invite on my test self-hosted instance, I see this error: Jobs::HandledExceptionWrapper: Wrapped Socket::ResolutionError: getaddrinfo: No address associated with hostname And this notice in the dashboard [CleanShot 2026-01-28 at 14.25.38@2x] [image] Canapin: Jobs::CallDiscourseHub Also, the failure on this one is not related to email. Do you have more info on this from /logs?

Hmm, neither look related to a plugin. I’ll update my instance (it’s 3 weeks old) and see if I see the same issues.

I guess Disable emails must be yes on those.

Right that might be the cause. It should be automatically set to “No” “Yes” when installing without SMTP I guess?

[image] Canapin: It should be automatically set to “No” when installing without SMTP I guess? You mean Yes, as the setting is to “Disable”. It should yes, but when you do that there is a super annoying global banner screaming that emails are disabled.

Je suppose que Disable emails doit être yes sur ceux-là.
