Unable to use certain apps or Webpages while on my Mobile Network

2: Seeker

Hello, so recently i have been unable to use apps such as Twitter or Discord while using my mobile data, but they work fine when using any WiFi connection

Other apps such as Pokemon Go works perfecly fine though.

I have since tried connecting to a VPN and then I am able to use them completely fine, but only when I am connected to the VPN.


When loading some webpages i get the error: net:err_cert_authority_invalid


I really would like this issue fixed as it used to work fine, and I feel like I have tried everything to fix it but to no avail.

Hi @ryan1993uk 


As well as clearing all your cookies and history, I would like to suggest refreshing your data connection on the network.  This is done by going into your wireless and carrier settings, carrier, turnoff off automatic and do a manual for available networks, select an alternative network, wait for it to reject the request and back onto Vodafone.


You can also text WEB to 40127, this will download the correct network APN settings and update your SIM on the network.
