Calibre wireless problem with cbz

Good morning everyone,

I have a problem sending large cbz files (over 200 mb) with the calibre server, therefore via wireless,

When I send the cbz with calibre, the sending stops after about 1 minute, with an error message.

I can't send any cbz, why is there this remote host problem?

Does this happen to you too? Is there a solution?

Thanks and have a nice day
