Hi, tacking onto this to get some assistance.
I've recently come across vanguard error 185, which doesn't let me access certain things online. For example, while I can access the shop in the client and start a game, I can't see match history. Other things I can't access include:
old.reddit (but I can access new.reddit)
escape from tarkov servers (my game gets stuck at "loading profile data" screen)
I also had a blue screen crash during a tft game. I have tried several restarts, but the problem persists on both my normal network and my hotspot
Could you try exiting Vanguard (right click Vanguard in the system tray and select Exit Vanguard) and then trying Ctrl+R on old.reddit to do a hard refresh and see if it still fails to load? Just on reading this, it sounds more like you're having an internet issue that caused the 185, but due to how it looked on your machine it feels like it was the 185 that caused the internet issue. Vanguard can't impact things like website access and wouldn't be doing any actions when you play other games. This would help confirm that Vanguard wasn't causing those hiccups.
