I have tried restarting my router, restarting my computer, uninstalling and reinstalling the app and it will not log in.
At the time of this it was just working an hour ago then, while I was in game (modern warfare) the game crashed and since i have had nothing but issues getting it to work.
Hey there Narulu! Thank you for reaching out, as it can understandably be frustrating to have a technical issue occur when simply trying to enjoy your gaming time. Being unable to connect to the Battle.net Desktop App can have a few causes ranging from corrupted local files to a network-related problem. Try the following to narrow this down further:
Try a DNS Flush to clear out any corrupted or stagnate data.
Fully update or temporarily uninstall security programs which may be interfering with your connection to the server(s). More information on troubleshooting security applications here, if curious.
Test an alternate network such as a mobile hotspot to determine whether the problem is isolated to your current network.
If you’re still unable to connect, please run a WinMTR network test so that we can further investigate the problem. Here are the instructions:
Start the test and launch the Battle.net Desktop App. Ensure the error occurs while the winMTR tool is running.
After recording data for about 5 minutes, click “export text” and save the winMTR file in an easy to find location.
Once you have that made, open the file. You’ll need to copy and paste the contents of the Text document into the post, and put four Tilde (~) marks above the winMTR. It’ll look like this:
