Apart from my appreciation, still nothing has changed with the symptom so far: Using any WebID I know, I am still hitting a solid:server Error page because of: { [HTTPError: Access to https://solid.durdik.ch:8443\index.html requires authorization]..., cf. Fig.8a, eventually making for No permission to access this resource: You are currently logged in as https://solid.durdik.ch:8443/profile/card#me, but do not have permission to access https://solid.durdik.ch:8443/, cf. Fig.13.
With full details, straight after its installation by the npm package manager, a command line client included as a recommended feature in Node.js installer that interacts with a remote registry, and starting the NSS prototype, it is asking the owner for log in and implicitly lets it seem like his (possibly alternative) registration was an option. Playing with it around, you are inter alia presented with a webpage with URI https://solid.durdik.ch:8443/common/popup.html and a button labeled Log in with solid.durdik.ch:8443. However, the button is dead preposterous to reason. Whatever else you do and wherever you go, the NSS at its best keeps insisting on No permission to access this resource: You are currently logged in as https://solid.durdik.ch:8443/profile/card#me, but do not have permission to access https://solid.durdik.ch:8443/.
Now, this message is incorporated also in intermittently operated nssforum.durdik.ch/. Take note of the fact that references (links) above still may shift over time.
Before extending this topic at Setting Up a Solid Server on a Windows Machine - Server Administration - Solid Community Forum.htm to the intermittently operated nssforum.durdik.ch/, I reported on unsuccessful switching to my WebID https://[user name].solid.community/profile/card#me after redefining the Web Access Control (WAC) acl:agent in the relevant *.acl files, i. e. [site URL] being my solid.community URL, when trying enlivening the cryptic NSS.
In fact, it was not me who wanted to use a solid.community WebID with the symptomatic NSS. The NSS does not authorize me as owner with https://solid.durdik.ch:8443/ based WebID to access it, so I just tried what came to my mind at that time. I did not incorporate this attempt in the aforementioned intermittently presented authoritative symptom description, since I feel in the meantime that using other than https://solid.durdik.ch:8443/ based owner's WebID is not what the poet meant to say. However, you better ask the poet, Justin.
Take note of the fact that new users as me can only put one image and only 2 links in a post.
