Same problem here. It started on Monday morning and is still present.
Of course as a community service we can not pretende anything, but the MQTT forwarding system at the moment is not usable, the data losses rate is simplty too high, I don’t know if we can help solve this in any way.
Yesterday I made some test using the HTTP integration, that forwarding system seems to work properly at moment. I suggest everyone to switch to it for the moment in order to have a better solution instead of simply polling TTN Data Storage.
Have you checked the status page? If nothing is listed, please use the ops channel on slack to notify TTN.
Quick note for people not on Slack: This seems to be resolved. It was caused by a bug (?) regarding uplink MQTT packets. See #ops on Slack for details.
Yes! I was up to publish it. I have been doing some testing during these couple days and all packets were shown in the application data. Thanks all.
