90002 errors when in Heaven on High

I'm getting constant 90002 error's when doing solo Heaven on High. Other internet applications work fine when the disconnects happen, usually have a stream open in the background while playing and it does not lag or stop.

Playing on a wired connection, tried resetting the networking stack on my PC through the bellow commands in CMD and I'm still getting the error. Seems to only happen late at night so it may just be a peak hours issue however it does happen when I'm playing during the day on the weekend as well.

I don't get the error when raiding it seems to only happen in Heaven on High solo. It's annoying when it happens when going for the floor 100 solo clear.

Reset network stack commands;
ipconfig /release
ipconfig /renew
ipconfig /flushdns
netsh int ip reset

Restarted my PC afterwards, any help would be appreciated.
