Question Cannot connect to Calibre on my laptop via WiFi from Calibre Companion - help needed

[Retzofrex]

When I try to connect using Wifi I get the error below. Cloud works as does Content Server but those do not show me the information as clearly as if I could connect using the WiFi connection. What I get is as follows...
Laptop is Windows10 up to date and tablet is a RCA Mavern Pro 11.6" tablet with a 32Gb SD card installed. HELP, please...

The problem isn't the device it is the program. You need to contact the company that makes the program to see if there is a fix for it or if they can help you resolve it.

They may well have instructions already on their site on how to resolve such issues.

If you can connect to anything and everything else, then the program is the problem and only they can help.

Which program? Both Calibre and Calibre Companion have been informed about this issue and neither has responded.

I don't know that particular program, so I can't say which one is the cause. However you should be able to tell on your computer which is associated with those files that you are getting errors for.
