It should show which groups you are subscribed to. Does it include LTspice? If not, click on 'Find or create a group' on the top bar. Put 'LTspice' in the Search box, top right. That should get you on the right track.

There are many ways to get those wrong.

Are you currently logged-in to Groups.io?? If you check the upper right corner, does it show your name there, or does it say "Sign Up" or "Log In" instead?? Did you click on a link to go directly to either of those two URLs?? Or did you start at the group's main webpage ( /g/LTspice) and then click "Files" or "Photos" in the left column?? Can you navigate into "Files", and see that the "Temp" folder is there, before clicking it? ?
It may be a security thing.
Perhaps.? Was this from your home PC or in a work environment?? It might be a firewall on your end.

As for the LDMOS model issue, it seems that it is a separate question, yes?? (I've changed the Subject line.)

What country are you in? A few countries appear to be blocked from the Files area, judging from reports from a few group members.
If that's not the case, you should figure out what the problem is. Can you download files from anywhere else?
The PD85004 model is simple and derived from the datasheet using the LTspice proprietary VDMOS model. It won't be perfect because the PD85004 is a lateral MOSFET, not vertical, but it was adequate for what I wanted at the time:
.model PD85004 VDMOS(Vto=2.6 KP=0.73 lambda=0.03
+ Rd=0 Rg=5 Rs=1.5
+ mtriode=0.5
+ Cgdmax=3.4p Cgdmin=0.93p A=0.35
+ Cjo=26p Vj=0.642 M=0.24)
You can use this with LTspice's standard NMOS symbol.

So you looked and can't find it. You can't find it because it isn't there. If you got the name right, whoever uploaded it, may have deleted it. Members can do this.
Pity you aren't looking for the PD85004. I made a model for that.

Do you get get an error message?
Are you trying to do this on a work computer? Some companies' IT
policies prevent downloading.
One other possibility is that you're trying to access the file by
clicking on a link in a group message. Files in the Temp area don't
stay there very long (the clue is in the folder name). Linked file
that are no longer in Temp will have been moved, but still
accessible.
Go to the Files
area. Copy-paste the file name into the search box in the top right
corner, and click the magnifying glass icon. Hopefully, it will be
in listed in the search results.
