Multiple games matchmaking "messes up"?

I'd have to find a time where I can separately test that since other people need to use the internet throughout the day for stuff more important than me playing a game so that I would have to look into at a different time.

But I can share the actual examples of the problem happening so you can at least see what is going on.

EXAMPLE 1: This was 2 years ago, I was having other problems which could have lead to this but the fact that the same situation still happens means whatever was fixed previously wasn't a solution for this specific problem either.

EXAMPLE 2: This was 7 months ago, in this example you can see that I DON'T have the connection filters set to a higher standard, meaning it should try to match me with ANYONE and yet it was messing up anyway.

EXAMPLE 3: This was less than a month ago, in this example you can see the connecting looping on the left side of the screen, previously I had played different people for over 1 hour and then it starts acting like this. And this happens "regularly" each time I play this game, it is like it just stops working for no reason and feels similar to the above examples in an entirely different game.
