Timeout issues when Secure DNS is set (Solved)

For the past 3-4 hours or so I’ve been getting timeout errors on certain websites (ex. Youtube, Jisho.org, Twitter to an extent, Discord won’t connect either) but not others (ex. Google, DuckDuckGo) when the Secure DNS is set on my router. It’s an issue I’ve had sporadically before, but not for this long. I had to switch back to the automatic to access those websites again, but I really need the Secure DNS. What should I do?

EDIT: Update - 12 hours later I can access those sites again, but Discord still doesn’t work.

EDIT 2: DNS now works correctly again, please delete this thread.
