Hello
I have installed Kodi 18 Leia on my PC.
Yatse doesn’t seem to be able to handle it anymore, the movie library can no longer be updated and pictures are no longer downloaded.
On my S7 and on my Tablet the same error.
HTTP FAILED: java.net.SocketTimeoutException: failed to connect to /192.168.1.102 (port 8080) from /192.168.1.140 (port 56592) after 5000ms
Your Kodi had an issue during update, triple check it’s IP and all settings as per the Wiki.
Kodi 18 is fully supported 
Made a cleanup of the database in Kodi since then it works reasonably well.
Every now and then yatze stops downloading the pictures with a “download error”.)
You excerpt of the log.

Your Kodi gives url for images that does not exist, clean your Kodi library
I’ve already used onboard resources to clean up the database.
Can you recommend anything?
Java Timeout happened to me. Turned my VPN OFF, that solved it…
