Troubleshooting & FAQ (2)
TroubleshootingWhy does Komga return 400 Bad Request when syncing reading state for Kobo store books?
This is a known issue with Komga's Kobo proxy. The fix is available on the koboproxy branch: https://github.com/gotson/komga/tree/koboproxy. Build Komga from that branch to resolve the 400 Bad Request error. Alternatively, the fix from PR #2291 also works. A permanent fix will be included in a future release.
TroubleshootingWhy do Komga series sharing labels disappear after restarting the Docker container when using an NFS mount for the library?
This is caused by an NFS mount race condition. If the NFS share is not fully mounted before Komga starts, the library scan sees an empty directory and treats it as a new, empty library. This triggers a full library rebuild with new series IDs, orphaning existing series sharing labels and other metadata linked to the old IDs. To prevent this, configure the library directory to a sub-directory within the NFS mount (e.g., /data/komga instead of the mount root /data). When the mount is missing, Komga will then detect the library folder as unavailable rather than empty, preserving existing series IDs and metadata.
