“EDIT: I deleted the CNAME and re-added it, then set my certificate to flexible then changed it back to full and now it works! Spent an hour trying to fix this, and it took all of 10 seconds to fix it. I have no idea what happened though.” @oash
This worked for me too, missed the solution on first read, although I also toggled it “off” before before “flexible”.
After doing that and renabling the page rule as above everything started working within 15-20 minutes. It’s not clear if this is a Cloudflare problem or an Obsidian problem but this turned a 5 minute job into an hours long nightmare.
