My iPhone "Cannot Verify Server Identity"! Here's The Fix!

Matt – STAY AWAY – I had a couple thousand dollars and 100+ hours of my own work invested in two websites that I hosted with them, along with thousands of critical work related emails. They upgraded the hosting server that my account was on and transferred the wrong files when they switched out the hard drives and all of my data was wiped. They then threw out the old hard drives so all of my work was gone. STAY AWAY FROM THIS HOST. STAY AS FAR AWAY AS YOU CAN.

David and David explain what to do when your iPhone says “Cannot Verify Server Identity”.

0:40 Close And Reopen Mail App
1:09 Check Date & Time Settings
2:13 Try Using Data AND Wi-Fi
3:50 Reset All Settings
4:18 DFU Restore
