Bug description

Read receipts and messages are not synced back to Android device. I think this has something to do with the proxy settings on my work computer. I have setup proxy environment variables in the Windows settings. Specifically the following:

http_proxy = http://proxy.<name>.com/<port>
https_proxy = http://proxy.<name>.com/<port>

Steps to reproduce

1. Link desktop to android
2. Send message
3. Sent message not linked to android device and reading message on Android does not mark as read on Windows.

Actual result:

1. Read reciepts not synced between devices
2. Sent messages not linked from Windows to Android.

Expected result:

Read status and messages should sync between devices.
