Thing is upnp is just for auto port forwarding, if the main node has a static ip and ports are forwarded it should be working even with upnp off.
It’s worth trying, but should be fine as is I’d have thought.
Searching the forum using term " upnp " multiple threads of ppl having upnp off and farming just fine.
Possibly port 8447 should also be open.
Alas it seems not, 8447 is internal for farmer to harvester.
Upnp should not be necessary if you forwarded port 8444 in the router.
Upnp is considered pretty risky security wise because (if it is enabled in your router) any application on your pc can open any ports.
Port 8447 is not used outside your local network. An open port in a router is also an additional security risk, I would close it.
I’m not convinced it is a router issue, other things seem to be out or order also.
Your Farm sections reports some 368TiB of plots, but in the Plots section none is shown and you are invited to ADD A PLOT…
Or do they show up, but is your screenprint just moments before?
If they do show up, I remember there is an Advanced Options item at the very end when you scroll down.
Not sure it was in the Plot or Farm section but I’ve seen a warning there when the Client does not have the right keys for the plots it has found.
So considering your issue, are you very sure you entered the correct 24 word mnemonics?
You could also do a chia plots check in CLI to be sure.
In Windows I believe you have to start Windows Powershell (right click the Windows Start button) and then cd to AppData\Local\chia-blockchain\app-1.2.11\resources\app.asar.unpacked\daemon
A chia plots check -g X: would check all plots on your X drive and report issues (like missing keys).
(Not a Windows user for Chia myself, so any corrections on path or command are welcome;-)
If you want to check the wallet/mnemonics, easiest is to go to Keys section in the GUI and click the eye-symbol in the Private key block. This shows the words entered to compare with your mnemonics as known.
I see (most of) your plots have a pool contract address, so NFT plots.
Are you self pooling or in a pool? And before the windows crash?
Does the Pool tab in the GUI also report the number of plots? Is the Plot NFT there?
Could you without the launcher ID and pay-out address visible do a screenshot please?
And did you try/succeed with the chia plots check command in CLI/Powershell?
