Seems specific to Mailjet, migrated to SendGrid now and all working.

medmunds commented 3 years ago

That's very odd. This seems like a low level networking issue, not something related to Anymail.

I wonder if you were experiencing (virtual) hardware issues or some other problem with outbound networking? Were other outgoing https requests from this machine working during the same time period? (And/or if you temporarily switch back to Mailjet, does the problem still occur?)

FWIW, Anymail live integration tests run weekly on Thursdays, and the one last Thursday was able to send through Mailjet without any problems.

aliaksei135 commented 3 years ago

Unfortunately I haven't had the bandwidth to test this. I'm happy to write it off as misconfiguration from my side since the integration tests pass.

I'll close this, thanks for your help!
