Web browser not working despite wifi connection
I get regularly some problem of connection with the android web browser.
When I am connectd to wifi, some applications connect (what app, skype) but some others no (shazam, tuneIn).
In addition when I start the web browser, the load bar remains stuck at 10% and the screen displays "webpage not available".
Do you have any idea to solve this issue?
For information I am using a VPN but the issue happen also when I disconnect it !
Thanks for your help and advice.
