Failure of Kia Connected Service?

Hello! My Kia Carens (EZ 03/2017) surprised me a little bit: When starting an approximately one-hour journey, the infotainment connected to my smartphone via Wi-Fi and not only indicated the WLAN connection that had been created, but also that it had downloaded online data (stau, radar, weather). Everything as normal and just like in the last few days… At some point during the journey, however, I suddenly realized that the WLAN-Emp The radar warning sign on the Navi map was gone again, traffic jam data was only shown with the “normal” TMC symbol again and no traffic and weather data was displayed via the info button. When clicking on it instead a message appeared in the display, according to which there was allegedly a “network error”. I first tried a restart – and both from the Smartph one as well as the infotainment – but it didn’t help anything. In addition to the display for the full WLAN reception, only the aforementioned “network error” was displayed as soon as I wanted to use an online service. I then set up my mobile WLAN LTE router as a receiver – but also after its setup the aforementioned scenario again. Same then even when I booked the infotainment in my own WLAN at home on the doorstep. Everywhere best WLAN reception – but otherwise only “network errors”. Both the smartphone, as well as the mobile WLAN LTE router and even more so my home WLAN had really best internet reception… As a result, I exclude a mistake on my smartphone (or one of the other two WLAN networks). Can it be that maybe the Kia Connect server has failed instead? Did other such “network errors”? I would be happy about feedback…
