I have Samsung Galaxy S9 with Android 9. Once in a few days happens to me that I have no internet connection on this device. Cannot load any page in Chrome, cannot connect in Speedtest app. Device is connected to wifi on which other devices(nb, other smarthones) work. The same is true for mobile data using 4G. Phone is connected to the network but could not load anything. But what is weird, I can succesfully connect to my vpn and then I can load anything without problem. Disconnecting from vpn resumes the problem. I have tried Kaspersky and Eset antivirus with no findinds. Also reset network settings with no success. Any ideas?
