Edit: That worked for me, thanks a lot I appreciate your help!
Yes, there is the 300016 failure for D3 when connecting. I get all the way to retrieving the hero list then it fails. I did the winMTR test and here is the data.

While connective issues seemed to have been resolved from my end, now it’s getting stuck at Retrieving hero list. The only work around I have, so far, is to exit out then relaunch the game to be able to play the game. Although there is a workaround, it kind of gets annoying that I have to launch the game twice to play the game.
The symptoms of the initial issue was issues connecting to Blizzard services or the 3003 error. As this has been resolved, this thread has been closed.
For those experiencing the 395000 or the 300016 errors, please refer to the main thread here.
If you are experiencing a different issue, please create a new thread.
