Per Quarkboy on Discord, /app/v1 went away, and third party developers need to move to /app/v2 . It's supposedly mostly compatible, and the few minor differences "should be easy to figure out by playing with it"

I imagine that means the differences are mostly in the responses and not the requests.

Thank you for the bug report.

I will try to update today or this week-end. In the meantime, it seems the fix indicated by @justdave should work: At the top of the jncep/jnclabs.py file, replace the value of LABS_API_PATH_BASE from /app/v1 to /app/v2.

There are a few minor changes that needs to be fixed in the code

• api_path updated from /v1 to /v2
• embed path updated from /embed to /embed/v2
• series_id updated from legacyId to id
• tracked series_id needs to be updated from legacyId to new id
• cdn-urls are now both https://cdn.j-novel.club and https://d2dq7ifhe7bu0f.cloudfront.net

Think that was all I needed to change to get it to work. Only tried downloading epub, tracked new series and update from tracked file. Havn't tried the eu-version either.
