Sidekiq can't update gravatars, delays notification emails

Hello

I noticed that the subscriptions emails are being sent with a long delay (many hours).
I’ve been seeing in Sidekiq that the “UpdateGravatars” job fails (presumably because of my corporate proxy), and the multiple replies are flooding the queue.

Is there a way to disable this job, or make Sidekiq use the proxy ?

Thanks

Search site settings for gravatar and disable them. SSO overrides avatar might also help.

Thank you, it worked.
I just had to remove the remaining jobs already scheduled.
