Thanks for responding and checking your instance. My original install had both the flaresolverr and tachidesk containers in bridge network mode. As per your suggestion I have setup a custom network manga and configured the flaresolverr and tachidesk to have a network mode of "Custom: Manga". Even with this change, I am still having the 0.0.0.0:443 error for Mangakakalot but no issues with Mangafox. I am using the flaresolverr Official container from the Apps directory. I tried to do some debugging with help of Gemini: Verified that the flaresolverr instance was working by browsing to the server ip address and port. Got a "Flaresolverr is ready" msg in the JSON response. This indicates that flaresolverr is working. I used the curl command "curl -X POST http://flaresolverr:8191/v1 -H "Content-Type: application/json" -d '{"cmd": "request.get", "url": "https://www.mangakakalot.com", "maxTimeout": 60000}'" from the console of my Tachidesk instance to verify the container can connect. I see a proper webpage. I then configured flaresolver url to "http://flaresolverr:8191" in the tachidesk container, restarted and got the following in the logs: Tachidesk Log: 16:47:58.901 [DefaultDispatcher-worker-1] DEBUG suwayomi.tachidesk.manga.impl.util.PackageTools -- loading jar with path: /home/suwayomi/.local/share/Tachidesk/extensions/tachiyomi-en.mangakakalot-v1.4.21.jar
