Recently I was getting banner_title_oups when I tried to start the My Renault app (preheat the car in the winter is just nice 😉).
Uninstall, reinstall did not change anything; I did not even get the sign-in screen! Weird.
After a lot of tinkering around it worked! But why? I was not in the WiFi anymore – and this is the culprit:
I run adblocking for the whole home network (aka PiHole or Adguard); something must have changed in the Adlists or in the app itself.
I granted access to the whole device now, if I get down the rabbit hole on what domain is causing the issue – I will update.
If you have the same problem: be sure to check any adblocking software you may run on your device or even off the device. Switching DNS and network can also help to troubleshoot.
I had to whitelist “socialize.eu1.gigya.com”, which was the domain blocked by Pihole at My Renault startup to be able to use the app within my wifi again.
