This issue has been bothering me for a while, I guess it's time to post it now.
At certain hours of the day, I can't connect to osu in-game. It's always the same hours. The site always works fine.
I believe the problem has something to do with my ISP, as I've asked other people who have other ISPs in my country and they're able to connect to osu in-game no problem through the entire day.
Between 2AM and 11AM, I can always connect fine and play multiplayer. In the rest of the day, the game fails to connect.
This is what I see:

Here's the trace route results from osu.ppy.sh and cho.ppy.sh (this is being taken at 11PM):

I tried opening the ports mentioned in the op, it had zero effect on the matter. For the record, I have multiple ports opened for purposes of direct-ip hosting on other games (that need other ports) and the port opening has effect and works correctly for them.
Any help would be appreciated. I'd like to be able to play osu at home in normal hours.
