GOAWAY errors

[maxmijn]

We have consistently been getting this error on about 1 out of 100 notifications we sent. Any idea how we can fix this?

apn write failed: New streams cannot be created after receiving a GOAWAY

Thanks for opening this issue!

Looks like a rate limit, or maybe the stream is just closed.

Thanks for looking into this!

If I look at the error codes that APNS should be returning I would expect some more information if running into a rate limit. I can't really find anything else about this error apart from some fix in an unmaintained version of this project. Do you know any other way I can debug why this is happening and perhaps prevent this in the future?

I send notifications every day and consistently encounter this error. To prevent redundancy, I refrain from retrying. Could you please help me understand why this is happening and suggest ways to reduce the error rate?

If anyone wants to open a PR here with the fixes, then we can merge.

I believe those fixes are already implemented in this library.

Got it, in that case it would be great if someone who is experiencing this issue could investigate some more, possibly manually add a log line to where this issue occurs so we can get more info in case the apn library swallows some of the error information.
