Can't reconnect to ranked match

I was in the middle of my match and we just pushed mid inhib. We then decided to baron and on my way to baron my computer completely froze up on me so I had to do a hard shutdown and reboot the computer. I was able to get back on league within a minute to minute and a half and I wasn't able to rejoin my match. The match counted as a loss for me and I don't think there was any way that we had lost within that minute that I was gone.

I'm not sure what the bug is but if anybody else is having this issue it would be nice to know it's not just me.
