We received a status of "blacklisted" on a RingCentral token. What does this mean, and how can we prevent this?

We received a status of "blacklisted" on a RingCentral token. The reason given was "I/O operation is failed." 

The app has been running for 6+ months and this is the first time I have seen this. 

What does this mean, and how can we prevent this?

Hi Lee,


Since your app has been running in the production environment, this type of problem should be addressed urgently by submitting a support ticket where our dedicated support engineers can help you more timely.


But be prepared for more information if you have such as a log file with other error code/details, your app type and authentication method (3-legged or password flow) etc.

Hi Lee,

How is the issue going? You said "We received a status of "blacklisted" on a RingCentral token. The reason given was "I/O operation is failed."

How did you receive that status? Is it the response of some API call? If so, could you please tell me what is the API call? Or you can show me some code snippets. I've never heard of this issue before. Thanks.

Tyler

These situations can be best handled by the developer support team from the back-end who can investigate the actual root cause.

You need to provide some more info regarding the API you are using, your oauth grant_type, your app_id etc
