Status Events for PubNub Python-Twisted SDK


NOTICE: Based on current web trends and our own usage data, PubNub's Python Twisted SDK is deprecated as of May 1, 2019. Deprecation means we will no longer be updating the Python Twisted SDK but will continue to support users currently using it. Please feel free to use our other Python SDK offerings as they will continue to be supported and maintained. If you would like to use the Python Twisted SDK specifically, we would love to work with you on keeping this project alive!

There is set of error categories which is returned by PubNub client through API completion blocks or delegate callbacks. Access to category can be done using status category property.

Delegate callbacks related to subscribe API usage and allow to handle real-time updates and errors.


PNAccessDeniedCategoryThe SDK will announce this error when the Access Manager does not allow the publish to a channel.
PNBadRequestCategoryPubNub API server was unable to parse SDK request correctly. A big chance of internal SDK error, so let us know if you stumbled into it.
PNAcknowledgmentCategoryDefault category for successfully completed transactional request.
PNTimeoutCategoryProcessing has failed because of request time out.


PNTimeoutCategoryFailure to establish a connection to PubNub due to a timeout.
PNBadRequestCategoryThe server responded with a bad response error because the request is malformed.
PNNetworkIssuesCategoryA subscribe event experienced an exception when running. The SDK isn't able to reach the PubNub Data Stream Network. This may be due to many reasons, such as: the machine or device isn't connected to the internet; the internet connection has been lost; your internet service provider is having trouble; or, perhaps the SDK is behind a proxy.
PNReconnectedCategoryThe SDK was able to reconnect to PubNub.
PNConnectedCategorySDK subscribed with a new mix of channels. This is fired every time the channel or channel group mix changes.
