Intersting, I get a 404 error.
2026-08-02T15:55:19Z [warning] Error reported while validating credentials: “unexpected status code: 404, body: \n\n404 Not Found\n\n
The requested URL was not found on this server.
\n\n”The logs don’t show the requested URL, I’ll check my server logs. Could it be related to the fact that my nextcloud instance isn’t located in the server root but under /nextcloud?
Yep, that’s probably it. Though just checked that my app won’t work with a Nextcloud instance under a custom path. Will publish a fix shortly.
If recipes contain images, the logs show a failure (406 Not Acceptable).
I think this is because the request.go sets Accept: application/json , so will not receive images.
Adding this fixes the error, but later of course parsing json fails (because it’s not json).
req.Header.Set("Accept", "image/*")
Can confirm, the /nextcloud is missing in the request:
[02/Aug/2026:18:14:34 +0200] “GET /apps/cookbook/api/v1/config HTTP/2.0” 404 196
Btw: This is the fastest support ever 
It seems to work for me and I only get 406 when the image does not actually exist.
Released on OpenRepos
Still no luck. Server logs show that /nextcloud is now prepended, but still get 404 error:
2026-08-02T17:04:39Z [warning] Error reported while validating credentials: “unexpected status code: 404, body: {"folder":"\/Recipes","update_interval":5,"print_image":true,"visibleInfoBlocks":{"preparation-time":true,"cooking-time":true,"total-time":true,"nutrition-information":true,"tools":true}}”
Can you contact me in PM with details? Even better if you could create me some credentials which I could test it with.
PM sent. (+20 characters)
Can we have some screenshots on OpenRepos please?
Added the screenshots
I successfully signed up for NC. The recipes were there, I couldn’t import recipes from Chefkoch (Could not load recipes.) When I reopened the app, the recipes were gone. They are still there in NC cookbook (web).
Any errors to report? See this message: Cookbook support thread - #12 by Rikudou_Sennin
Thanks to Rikudou_Sennin, I can now login.
I needed to add “/index,php” to the URL - didn’t do that as I don’t recall any other app that needs this.
Wanted to post this here in case other users have the same issue.
