Sony Xerpia U Wifi is on but pages dont Load

[Anonymous]

The internet use to work fine on the phone, but as of late pages no longer load up though the same wifi conntection is still on.
Get a message box saying this when I click on internet pages eg facebook (also any internet page like google)
"Cannot retrieve notications. Please try again later. [Hostname in cerficate didnt match.
<api-read.facebook.com>!=<www.btopenzone.com>]

With other pages either message comes up, or just dont load. Any help would be great.
Thank you.

First thing to try is setting it up again by texting ACTIVE to 2020, save the settings and reboot the phone.

Do you have an account with BT which you need in order to use their wi-fi?

Could you have connected to a different one to the one you were using?
