I think they changed the api. 404 Error for changing profile, too.

After disabling profile PIN protection, I was able to navigate in movie library...
(This is just a workaround, not a solved problem !!)
But if I choose a movie, another error occurs:
https://paste.kodi.tv/otufeyawaf.kodi
EDIT:
THIS LAST ISSUE IS SOLVED. I had to reset my ESN in "expert settings"
Mannshoch commentedon Mar 2, 2026
What doea this esn. and what happens if i reset it?
screenagerbe commentedon Mar 4, 2026
Got the same error, but a different scenario.
Everything is working fine, but we're locked into the Kids profile which has no PIN configured.
When we try to change profile we get the same 404 Error.
I'll try to generate a new NFAuthentication.key and see what gives.
Lamarqe commentedon Mar 6, 2026
After generating a new NFAuthentication.key, I can not watch any steam anymore.
It always gives me: MSL error
licensedManifest/playapi-445: Playback not permitted by Content Usage Policies
Even after generating new ESN for Widewine...
Any ideas? I initially thought it might be about wrong inputstream adaptive resolution settings, but also changing to 480p did not resolve the issue.

I have the same error when trying to change profile. This is on 1.23.5 on OSMC.
The URL is

The same issue when changing profiles occurs to me with 1.23.5 on Kodi. But with followind steps, I was able to use the plugin with the main profile:
after theses steps, the default (main) profile was selected in the plugin and I am able to use this profile including management of "my list" in this profile.
However, changing to another profile does not work.
aristotelesweb commentedon Apr 18, 2026
I got this IPC callback raised exception now for a couple of months on kod 1.23.5. After reading this thread I created a new key (by instructions of patricksrentsch, thanks) and got the "MSL error Playback not permitted by Content Usage Policies" error. I did the procedure two times, with the same MSL error.
patricksrentsch commentedon Apr 18, 2026
Meanwhile, I switched to the adapted version in the pull-request
#1783
There, the API used has changed. So far,
i can use the complete functionality of NF, slthough I have not re-activated the PIN for the different accounts. Perhaps you can try this.
Lamarqe commentedon Apr 18, 2026
Yes, I can confirm. #1783 solves the issue.
Important for me is to keep the existing NFAuthentication Key, as recreating it will cause the MSL playback issue I mentioned above. However, this is an additional, but unrelated problem.
Luckily I had kept a backup of the addon data before replacing it with a newly generated one.
Restoring the backup and applying the changes of the linked PR has finally brought back Netflix on Kodi for me.
aristotelesweb commentedon Apr 18, 2026
Thanks for the quick repsonse and help.. Unfortunately I don't have the old NFAuth key. I replaced the files from the 1783 version over the currently installed netflix addon and still got the MSL playback issue. I checked I have the most recent input adaptive widivine version.

@Lamarqe : If the previous NFauthentication key is required then that is going to be an issue in two instances. 1) First time installers, who don't have an older setup. 2) When the authentication key eventually expires as it is designed to do!

Root cause: Netflix removed artwork nodes from the Falcor schema
The pathEvaluator 404 is caused by the add-on requesting artwork paths that no longer exist server-side. Any request containing one of these paths returns 404 for the entire batch, which is why all browsing breaks.
Reproduction
Captured a working pathEvaluator request from Chrome DevTools (Copy as cURL), then replayed it with individual paths substituted. Same cookies, same session, same endpoint:
path=["loco","componentSummary"] -> 200
path=["loco",{"from":0,"to":50},"componentSummary"] -> 200
path=["loco",{"from":0,"to":50},0,"reference",["title","summary"]] -> 200
path=["loco",{"from":0,"to":50},{"from":0,"to":0},"reference",[...]] -> 200
path=["loco",{"from":0,"to":50},0,"reference","boxarts",[...],"jpg","value"] -> 404
path=["loco",{"from":0,"to":50},0,"reference","interestingMoment",[...],"jpg","value"] -> 404
path=["loco",{"from":0,"to":50},0,"reference","artWorkByType",...,"png","value"] -> 404
path=["loco",{"from":0,"to":50},0,"reference","storyArt","_665x375","jpg","value"] -> 404
Artwork is not addressable under videos either:
path=["videos",81605886,"boxarts",["_665x375"],"jpg","value"] -> 404
path=["videos",81605886,"storyArt","_665x375","jpg","value"] -> 404
path=["videos",81605886,"artWorkByType",...,"png","value"] -> 404
path=["videos",81605886,"summary"] -> 200
path=["videos",81605886,"itemSummary"] -> 200
What replaced it
Artwork now arrives embedded in the itemSummary atom rather than as separate Falcor nodes. Current web client responses contain, inside itemSummary.value:
assets — keyed by role (logo, background), each with url, artWorkType, imageKey, width/height, tone
videoAssets — e.g. horizontalBackground with motionUrl, motionId, autoPlay
URLs are .webp, and the current client sends webp=true as a query param
The web client no longer requests artwork paths at all.
Things ruled out (all tested, all returned 200 when artwork paths were absent):
Session/cookie validity — add-on's own NetflixId/SecureNetflixId from COOKIES work fine
authURL — add-on's token accepted
User-Agent (tested Chrome 108 and 140)
x-netflix.* headers — not required
Body encoding (raw vs percent-encoded)
HTTP/1.1 vs HTTP/2
Kodi's bundled requests 2.31.0 / urllib3 2.2.3 / OpenSSL 3.5.4 — reproduces 200 outside Kodi with a non-artwork path set
Endpoint URL and query params — identical to the current web client
Unrelated bug found along the way
In http_requests.py, _prepare_request_properties():
pythonauth_data = f'authURL={self.auth_url}'
The authURL is inserted raw into an application/x-www-form-urlencoded body. Tokens containing /, +, or = are misparsed (+ becomes a space). Should be:
pythonauth_data = 'authURL=' + quote(self.auth_url, safe='')
Not the cause of the 404, but a real bug.
Environment: add-on 1.23.5+matrix.1, LibreELEC, Kodi 21.
shithead commentedon Oct 8, 2026
Adjacent work to the root cause @richardgoodin identified above (artwork nodes
removed from the Falcor schema): #1807 implements the replacement via Netflix'
GraphQL endpoint, and keeps a halving/blacklist layer for retired paths instead
of removing the artwork paths (the #1796 route).
Two additions to that analysis:
User-Agent: Kodi/20.0andsession cookies only (no browser fingerprint headers); complete artwork at the
same dimensions as the captures. Reproducible via
docs/graphql-probe.sh.itemSummarycard is used only as the poster fallback; theGraphQL
Imagenodes are the primary source.Branch + tests: #1807.
