Not quite true. There could be a connect to *something*, just not calibre. This happens all the time when "network security suites" are installed.

There is no firewall, just routing between the WLAN network 192.168.26.0/24 and the LAN 192.168.10.0/24. But there is no multicast between the networks. Therefore I configured fixed IP/Port in the CC.

The connect from the browser is done from the same device as the CC.

Any ideas?
Seriously, you have no firewall installed on the calibre computer or on any router between the device and the calibre computer?

Are you using HTTPS with a self-signed cert? CC does not support these. All the site certs, intermediate and otherwise, must be installed on the device running CC.

Is CC using exactly the same URL as you are typing into the browser? In other words, does http://192.168.10.7:8080/opds/ work in the browser? If you are doing some sort of reverse proxy then this URL might fail.

Send yourself a CC debug log (CC / Settings / Other / Send a debug log). That will tell you if CC thinks it connects but fails to send data, or if CC thinks it does not connect.

Some linux users have reported that linux thinks that calibre is doing a SYN flood. Turning on SYN cookies fixes that.

Other than these I don't know what else to suggest.
