The Manage Connections page shows a yellow stop sign for WiFi.
My WiFi diagnostics show a red cross for connecting under the blackberry infrastructure and theres nothing following IP Used or Address Used.
I know it's not my network as i have a public IP with no firewall or NAT.
There is an entry in the HRT for WiFi which goes to rcp.eu.blackberry.com:443 and another with just the IP.
I've tried some tests:
Using Carrier:
HTTP = 500 error
HTTPS = No connection
Using WiFI
HTTP = No connection
HTTPS = No connection
Whats also interesting is that if you try and connect to HTTPS using the ip for rcp.eu.blackberry.com then you get a certificate error which i would expect but it shows it can connect.
I also noticed that under security and TLS, it was defaulted to PROXY and there are no Trusted hosts, changing to HANDHELD shows no certificates.
Software is 4.3.0.67 (Which I totally love over 4.2!!!)
Could someone that has this working on O2 UK do a comparison?
Cheers!
