"DNS Probe Finsished No Internet" on Data Only after 5.1.1 Update

[AndyMac212]

I've loved having my Sony Xperia Z3 Compact until recently after the 5.1.1 update... Ever since I updated my phone, it has been having issues connecting to the internet using data.  The wifi works fine but when running on data after a few minutes I get the error "DNS Probe Finished No Internet."  

I contacted Sony and I tried all of the Sony Agent's suggestions (resetting the phone, reset button next to sim card, and full restart and update through the computer using the PC Companion).

I have seen people with this issue on other Android Forums but I thought I would try here... Has anyone else experienced this issue??  And even better, a solution?? (without sending in my phone to Sony because that takes weeks... and I feel like they won't "find anything wrong")

Just found this on another forum post and I think it relates to my problem so I am trying it out:

From reddit user FishStik5: Going into the APN settings and changing the APN protocol to iPv4 only (it was iPv6 before) seems to fix the problem. 

How to find the setting: Settings-> Wireless and Network / more -> Mobile networks -> APN -> T-mobile data -> APN protocol -> Set to IPv4.

This appears to fix the issue for me.
