My HTTP integration suddenly stopped working although it has been working fine for a couple of weeks. I tried to debug the connection to check whether there is a problem with my endpoint (hookbin.com) but it works correctly and receives messages from other sources. Also, I tried the same steps with another TTN account - there are no signs of any uplink on the Hookbin. Is it caused by some updates in TTN (policy, limits or something else) or there are some issues with TTN server?
Thanks to all of you for your answers!
