While we are retrieving data using box Rest-API's, getting exception(connection timed out: api.box.com/185.235.236.197:443) very frequently.

Initially we were getting 429 status code as request rate limit were exceeding, so we handled it by making less then 16 calls per second But now we are getting connection timeout exception without any status code.

We are getting below Exceptions :

Exception: 1

reactor.core.Exceptions$ErrorCallbackNotImplemented: io.netty.channel.ConnectTimeoutException: connection timed out: api.box.com/185.235.236.197:443

We really appreciate if any one can let us know the exact cause of these exceptions , so we can handle these exceptions in proper manner.

    Are you still encountering this issue? If so, can you provide me with the client ID and a specific example date/time/timezone of the issue so I can take a closer look at our logs?

    Hmm what error message dud you get during that time? The only errors I'm seeing are 400s related to tokens. Digging further into those the error is: invalid_client: The client credentials are invalid.

    Hi Kourtney,

    It's getting fail in first time and  while we retry the same API after few seconds it works fine for us.

    You seen 400s because the token get refreshed between the time frame I provided earlier. 

    can you please check again for the below time frame ?

    Time: between 2020-12-03 19:19:34.849  IST To   2020-12-03 19:19:49.716 IST

    The message we are getting is  [id: 0x895b1e8f, L:/10.100.130.59:52699 - R:api.box.com/185.235.236.197:443] The connection observed an error

    thanks,

    Hmm so "The connection observed an error" is not an error message Box will ever return. Is it possible to get more verbose logging that might show a specific error message that is coming from Box?

    I believe the root cause of the issue is still rate limiting. I can see you're exceeding the number of API calls per second per user with user ID 13735777247 at this time.
