I created an apiRest Full with node that works well in my project ionic, I access very well the browser and even some less android phone version 9 but higher than 9, I have the error :

"Http failure response for (api address): 0 Unknown Error "

Can some give me some solution track? Thank you for your answers ionic 5.2
