You did a reset of the router and then this happened? Sounds like the key changed when the router reset. From the screenshot it looks like you are using windows... No idea how to delete the old key on Windows but here's how to do it on linux (and it may point you in the right direction)...
Out of curiosity, what's your setup / process flow on this? A back up solution is intriguing as I've never considered doing it to the router's flash drive. Now that I think of it, it's a huge gap in my setup to not have this done regularly!
Out of curiosity, are you using the Unbound DNS addon? When I had this installed my printer stopped communicating with anything. Once I uninstalled Unbound it went back to normal. I had to stop using it because of this unfortunately. I never found a solution.
Does anyone else have an issue with printers when Unbound is running?
I've been running Unbound on my RT-AC68U and noticed nothing on my network can print to my Brother HL-3170CDW printer. As soon as I removed Unbound everything could print to it again.
On my linux systems I get "No suitable...

It claims all key generation is done in browser and nothing is sent externally but I cannot verify that myself. I've not used this but did bookmark it in case I wanted to play around with it in...
Do you have any browser level ad blockers running (Adblock, uBlock Origin, etc)? The router may have them whitelisted but they are getting stopped in browser.
I've found that every few weeks the Amazon app on phone stops working and I need to follow the blocking log to see what new domain is causing the issue. I've got about a dozen that I've had to add myself to get it working.
Tasker has integrated Wireguard support and it works great. Very simple to do. I've got it set up so any access point I connect to outside my home or travel router (which acts as a VPN client as well) switches on my wireguard profile to connect home. I'm running a wireguard server on a Odroid...
I'd give you the complete OPPOSITE advice! Give it a go! Next thing you know you'll be duel booting your system with Windows and Linux and getting in to real trouble!
Exactly... I picked up a ~$40 ODROID C2 and have it behind my AC68 acting as both an OpenVPN and WireGuard server. The whole purpose is to give me simplified and safe browsing while traveling (I stay in hotels often). I use WireGuard pretty much exclusively but fall back on OpenVPN...
Careful... ssh is a gateway drug. It will lead you places you never intended to go, often in the middle of the night, and you'll realize you have no idea how you got there.
