RpcError(UNKNOWN): Http response at 400 or 500 level, http status code: 0
Hi, I´m using Mailjet as SMTP Provider but I cannot get it working in my production environment. I get the error in the subject and it doesn´t seem to be the configuration, but the environment itself that fails. I have a Kubernetes cluster with nginx ingress as proxy reverse. I set the tlsMode to be "external" and enforced http2. I can configure a local docker instance without any problems, but like I´ve said, as soon as it gets installed on my prod cluster, I can´t send any mail at all. I´ve seen 3 posts on this forum mentioned this issue, but couldn´t find any solution yet.

This is a log from our ingress:
hey @Don Snacko welcome and thanks for your question, I never saw your any other message, as an alternative, have you tried setting up any other SMTP too?.
Hey @Rajat, indeed that was working!
I´ve tested an outlook account of mine and it just worked!
So, the question may be then, why is is not possible with Mailjet?
hey @Don Snacko not sure whats wrong with Mailjet, we didnt get any known issues as such on it, my bet if you are evaluating, then pls play around with things that works for you if it doesnt harms your workflow, I will check with my engineers if they know if anything's reported on mailjet
The interesting thing is, is that the mailjet provider is working on my local docker instance without any issues at all. I´ve tried to set up a generic smtp provider, but that wasn´t working either in PROD.
Thank you for time, I can stick to my o365 account for some time and we can find a solution later 😄
Okay, I did it - somehow. I´ve just changed the port to 588 out of curiosity - and it just worked in Prod 🤷♂️
