Issues, Workarounds & Localization

Ever since the server change I have this really annoying issue. In the afternoons the game will work great.

Then some time during the early evening (around 16:00 server time) I will have an impossible time to open the game when eg. trying to switch characters.

Launcher logs in perfectly.
Launcher launches client and it downloads bulk data etc.
Then it freezes up with a black screen before the character selection screen shows.

When running the log server, the logs end with:
Waiting for ballpark nn

nn goes from 1 to 30 and then it says:
Failed to get a valid ballpark in time after trying 30 times.

If I leave the client, it will eventually disconnect, saying socket is closed.

Eventually the game will work again, but only after a few hours.

This cycle repeats every day since the new server hardware.

I've tried clearing cache and settings to no avail.

Network diagnostics can ping everything and trace everything. All downloads work fine.

I've tried changing the port too - same issue.

I'm running out of ideas here.
