Failling sending emails with campains

I am not using OAuth to send campaing email I am using an email adress on an other domain with baisic auth. when sending test emails it works fine both on personal using OAuth and group using Basic Auth

So, I manually purged the email queues and restarted a campain from scratch and it worked fine.

not sure what happend there??

thank you all for your insights
