Frequest disconnections with error 1040

edited January 2014 in Native
Hi,

We're using Photon-AndroidNDK_v3-2-2-0_Could_SDK - not the most recent android SDK.
We're using the free plan (20 CCU) for development.

We're getting frequent disconnections while doing QA on our game, with error code 1040. I'm trying to investigate why.

Here's a log from a weird case:

Note the "going to resend pComand" and then "ACK w/o command!", and the many "skipped dispatching of old command".
The "ACK w/o command!" messages started appearing only after joining the second room.

Device had internet connection (original log contains successful HTTP requests app has made at that time).

Are we doing something wrong?
Can you point me at reasons why we're getting disconnections with error 1040? (not all cases are like the one above).

Thanks!

  • Hi natasky.

    This looks like you have a bad connection with a high jitter and a high latency between you clients and the used cloud region.

    Have you tried to use a different cloud region?

    Have you tried if connecting to a local Photon server instance instead of the Photon cloud makes a difference?

    Could you please log the values, that get returned by PhotonPeer::getRoundTripTime() and PhotonPeer::getRoundTripTimeVariance(), once every service() call?

    Please download and run winmtr: http://winmtr.net/ to check the connection quality between your clients and the cloud region and to find out which part of the route is the cause of the problem.
