Troubles with updating

In the last few days I’m having troubles updating game (i play on experimentals). Launcher outright fails after about a minute trying to DL game archive because it does so at 20kB/s (also, launcher self-update failed today, probably for the same reason). Using browser help somewhat, in a sense that I can DL the archive but it’s still going at those 20kb/s so it takes about 40 minutes to complete. I have no problems with my internet connections, can play online games, watch videos, etc.
So, what could possibly be a reason for this lag? Am I the only one having this problem?

Probably Github issues.

I’m having a similar problem where any time i try to launch the launcher it outright crashes.
