HTTP 406 Not Acceptable Errors #149

I'm seeing a lot of 406 errors being returned recently when trying to send mail. It's strange because I don't see where the "Accepts" header is being added to the requests made by this library, which from my understanding is what would be the cause of an HTTP 406 error. What's also odd is that it happens non-deterministically, where sometimes the message fails with this 406 error and other times the same message will succeed without issue:

SendGridClientError: (406, '<html>\r\n<head><title>406 Not Acceptable</title></head>\r\n<body bgcolor="white">\r\n<center><h1>406 Not Acceptable</h1></center>\r\n<hr><center>nginx</center>\r\n</body>\r\n</html>\r\n')

Same here. We're also using sendgrid-django, for what it's worth.

SendGridClientError: (406, '<html>\r\n<head><title>406 Not Acceptable</title></head>\r\n<body bgcolor="white">\r\n<center><h1>406 Not Acceptable</h1></center>\r\n<hr><center>nginx</center>\r\n</body>\r\n</html>\r\n')

@NickFranceschina looks like we are going to need to dig deeper to figure this one out.

Here is what we need: Please email [email protected] and include the specific steps to reproduce (i.e. send X amount of emails, using the following code)

Thanks!

Same problem here... What is the support issue number for this case ?

@cdurieux could you please also submit a detailed ticket? Currently, we can't reproduce this issue. Thanks!

This is still happening for us after the upgrade. This is on Google App Engine in case it matters.

@NickFranceschina

yes, we are also on Google App Engine. if I could send specific steps to reliably reproduce it, I would... but as OP stated, it's non-deterministic

This is not fixed. It is still failing inconsistently for me on GAE.

@afrosimon

I concur, still the same situation for us. Also on GAE.

@RahavLussato

same here, also on GAE

This should be resolved for all GAE users now. Sorry for the trouble.

Hi,
We are still facing this issue on GAE.

Interesting thing is, all errored emails were successfully sent after retrying again.

Please follow up and rectify it.

Hi,
We are facing the same issue. Sporadically and in a non deterministic way, we receive
HTTPError(<HTTPError 406: 'Not Acceptable'>)

Some precisions:

  • http-python-client version: 3.3.2
  • sendgrid: 6.7.0
  • First error on Apr 28th also (2021)

And the messages are not sent in our cases !
Could you reopen the issue and investigate plz ? Let me know what I can send you to help you understand what's happening

Hello 💻
I have the exact same problem. My config is http-python-client version: 3.3.2, sendgrid: 6.7.0
And like @SanghviChirag when I retry it by hand it works.

We just had this occur too whneing sending an email with sendgrid python client:

Failed to send message with http error status_code=406, reason=Not Acceptable, body=b'<html>\r\n<head><title>406 Not Acceptable</title></head>\r\n<body>\r\n<center><h1>406 Not Acceptable</h1></center>\r\n<hr><center>nginx</center>\r\n</body>\r\n</html>\r\n'

Our software automatically retried the same exact request 8 seconds later, and it succeeded 202.
