[Docker] Error importing comics Error 404 was created by LainX84

Hello,

I am experiencing issues with my current YACReaderLibraryServer configuration on Docker.

In short, it keeps giving me an error saying that it cannot import comics from my library. If I restart the Docker service, it seems to resolve the issue for a few minutes, but then it reappears.

These issues arose after replacing my NAS (from Qnap to Ugreen).
The connection between the NAS and the Linux machine is via NFS v3.
Mounts are configured as follows:

Code:

# Mount NFS
168.0.2:/volume1/Fumetteria/Manga /share/ugreen/yacreaderlibraryserver/comics/Manga nfs _netdev,noatime,async,nfsvers=3,tcp,rsize=1048576,wsize=1048576 0 0
168.0.2:/volume1/Fumetteria/Manhua /share/ugreen/yacreaderlibraryserver/comics/Manhua nfs _netdev,noatime,async,nfsvers=3,tcp,rsize=1048576,wsize=1048576 0 0
168.0.2:/volume1/Fumetteria/Manhwa /share/ugreen/yacreaderlibraryserver/comics/Manhwa nfs _netdev,noatime,async,nfsvers=3,tcp,rsize=1048576,wsize=1048576 0 0
168.0.2:/volume1/Fumetteria/Manhwa-to-Manga /share/ugreen/yacreaderlibraryserver/comics/Manhwa-to-Manga nfs _netdev,noatime,async,nfsvers=3,tcp,rsize=1048576,wsize=1048576 0 0
168.0.2:/volume1/Fumetteria/ArtBook /share/ugreen/yacreaderlibraryserver/comics/ArtBook nfs _netdev,noatime,async,nfsvers=3,tcp,rsize=1048576,wsize=1048576 0 0

I completely recreated (with a new database) the Docker version following these commands:

Code:

mkdir -p /home/matteo/YACReaderLibraryServer/{conf,db}

docker run -d \
  --name=YACReaderLibraryServer \
  -e PUID=1000 \
  -e PGID=10 \
  -e TZ=Europe/Rome \
  -p 9999:8080 \
  -v /home/matteo/YACReaderLibraryServer/conf:/config \
  -v /home/matteo/YACReaderLibraryServer/db:/comics/.yacreaderlibrary \
  -v /share/ugreen/yacreaderlibraryserver/comics/ArtBook:/comics/ArtBook \
  -v /share/ugreen/yacreaderlibraryserver/comics/Manga:/comics/Manga \
  -v /share/ugreen/yacreaderlibraryserver/comics/Manhua:/comics/Manhua \
  -v /share/ugreen/yacreaderlibraryserver/comics/Manhwa:/comics/Manhwa \
  -v /share/ugreen/yacreaderlibraryserver/comics/Manhwa-to-Manga:/comics/Manhwa-to-Manga \
  --restart unless-stopped \
  yacreader/yacreaderlibraryserver:latest

By doing so, the .yacreaderlibrary folder is located on the host, as are the configuration files, while the cbz files are on the NAS (with mechanical disks).

The service starts and I have successfully created the library and the service has started normally.

root@61c17d65dbfa:/# YACReaderLibraryServer list-libraries
Comics Library : /comics

From the logs, I see the following messages (I excluded the QR code):

If I try to view it from my browser, connecting to IP:9999 and searching (for example) for the first chapter of a comic I want to import, it finds it correctly:

Code:

Do you have any ideas that I've missed?
