Kobo Clara sync issue #2428

Closed exile259 closed 3 months ago

exile259 commented 2 years ago

Describe the bug/problem I am using the Linuxserver Calibre-web docker container with their SWAG nginx/letsencrypt container.I have followed the Nginx guide (https://github.com/janeczku/calibre-web/wiki/Setup-Reverse-Proxy), and configured my CW instance to allow sync for one bookshelf. Access logs show the sync attempt, but nothing ever syncs

To Reproduce Steps to reproduce the behavior:

  1. unlock Kobo
  2. Tap the sync button
  3. Tap Sync Now
  4. NO books are synced

Logfile

access logs: https://zerobin.net/?f7bc5221eb2269c0#02/aC1MdSjiVVlSsazmFjJtOmzSvhAqXT6o/fEB425c= Calibre logs: https://zerobin.net/?8e7415113c65b117#hX7AdBFj+irjs/Dw3S+lhvVKeO2rCFYPzm+j+IN4xQ0=

Here is my conf file for calibre. any deviation from the Nginx guide was to make the web portal function (following the instructions to remove the proxy_set_header and alter location resulted in no formatting being applied to the web portal)

#    proxy_set_header X-Scheme $scheme;
#    proxy_set_header X-Script-Name /calibre-web;

Expected behavior Calibre-web to sync expected shelf to my Kobo

Environment (please complete the following information):

Additional context Add any other context about the problem here. [e.g. access via reverse proxy, database background sync, special database location]

OzzieIsaacs commented 2 years ago

In both provided logfiles no request regarding kobo is logged, so all requests seem to be "lost between kobo and calibre-web".

Please checkout the procedure described here (https://github.com/janeczku/calibre-web/wiki/Kobo-Integration#checking-kobo-sync-content) to figure out if it's possible to access the kobo routines of calibre-web with a browser. The document is pretty new, so maybe there are bugs in it, so if it's not working out, please be patient and post the issue(s) here

Access logs show the sync attempt, but nothing ever syncs

Could you please tell me which line the sync shows, as I can't find it: image ?

simkin commented 2 years ago

Fore me the initial transfer also failed and all future sync attempts resulted in nothing as calibre-web assumed the sync was already completed successfully. Please try to force a full sync

And experiment with your external port: image

I am having the same problem too, I can't get sync working on my Clara HD, with a similar set up. I have a Docker container 

version: '3'

services:
  calibre:
    container_name: calibre
    image: lscr.io/linuxserver/calibre-web:latest
    environment:
      - PUID=1026

      - OAUTHLIB_RELAX_TOKEN_SCOPE=1 #optional
    volumes:
      - /volume1/docker/calibre/config:/config
      - /volume1/Calibre Library:/books
      - /volume1/docker/calibre/config/gmail.json:/app/calibre-web/gmail.json
    ports:
      - 8083:8083

        ipv4_address: 172.19.0.9

which is accessible through a reverse proxy

However, when I try to sync, the Clara HD says 'Sync failed, please try again' in my calibre-web.log I see the following:

Things I've tried:

Activated 'Force full kobo sync'; Created collection on my kobo with the same name as the shelve I'd like to sync, removed it later; Restarted the Clara HD; Restarted the Calibre-web container; Turned the option 'Proxy unknown requests to Kobo Store' off and on; Tried various ports for "Server External Port (for port forwarded API calls)" (ports 8083, 443, 80); Configured the Clara HD to sync locally, to bypass the reverse proxy; Turned off Adguard DNS filtering on my network.

All without luck so far. I haven't factory reset the Clara yet, because I have reading progress and books already on it, so I would rather not do that, as long as it is not necessary.

It turns out I just needed a rubber ducky to help me with debugging.

I had to add some proxy_buffer lines to my reverse proxy configuration, al stated in the documentation here:

proxy_buffer_size 128k;
proxy_buffers 4 256k;
proxy_busy_buffers_size 256k;

That solved my issue completely. I hope this could be useful for someone else too.
