Can't connect CC to Calibre using Samsung Nook

[pmatch1104]

In the past, I've been able to connect my CC app on my Samsung Nook to calibre via the wireless connection ... but it has been about a year since the last time I did. I've updated my calibre app on my laptop, made sure my CC app on my tablet is up to date, made sure my firewall is allowing "the main calibre program" through, and made sure both are using the same band on my WiFi. But I keep getting the "failed to connect" error message regarding the IP address. I've read through the Help instructions and nothing seems to fix the problem.

I'm not a very techy person but can follow detailed instructions. I remember having this same problem in the past, but not how I got it fixed. Any help you can give me will be greatly appreciated! Thanks.

I responded to your email with this:

The debug log indicates that the computer running calibre is not allowing connections from CC to calibre. The usual reasons for this are:

• The antivirus (AV) SW on the calibre machine (vast majority of cases)
• The firewall on the calibre computer is blocking CC (most of cases that are left)
• (Windows) The "network connection" is not set to "Private" (somewhat rare)
• The home WiFi router is set to block connections (rare)
• The home WiFi router needs to be rebooted (rare).

The debug log also says that the computer running calibre can respond to some of CC's "Are you there" requests but not connection requests. This implies (a lot) that the problem is the AV or the firewall. Without physical access to your network I can't say much more.

FWIW: windows and AV updates happen all the time, usually without telling you. Any update can break networking.

My first suggestion: reboot everything (the WiFi router, the Samsung device, and the computer running calibre in that order) and see if the problem goes away. My guess is that it won't. The next suggestion: do whatever you must do to add calibre as an exception to your AV and firewall. It might help to remove any existing exceptions before adding new ones.

No luck ... I rebooted the modem, the router, allowed access to AV and firewall with no results. I reran the debug reports. Do you see anything different?

One significant difference: the IP address of the computer running calibre has changed. It was 192.168.1.3, but is now 192.168.1.2. However, the CC debug log shows that *something* answered with 192.168.1.3. That is very strange.

Questions/comments:

• Is it possible that calibre is running on more than one computer on the network?
• What order did you do the reboots? Best is
  1. Turn off all devices
  2. Boot router
  3. Boot calibre computer
  4. Boot Samsung
• According to the CC debug log calibre is not answering one of CC's "Are you there" queries. This means that calibre is still being blocked by something.

You could try changing CC's wireless device connection settings to be the default. Unless something changes, such a change won't fix anything because CC is being given the incorrect IP address. One hopes that "something" will change.

Finally, although the "Debug device detection" report is interesting, it isn't the same sort of calibre debug log that you included in the first post. That other debug log is of interest because it indicates whether or not calibre "hears" CC's "are you there" messages.

Hello again ... and thank you for your patience and help.

I tried all of the steps above and still get the same results.

I sent the debug log from CC to the email address. I noticed that the number changed after rebooting everything. Any other suggestions?

Hallelujah!!! I got it fixed. The problem was my firewall network somehow got set to Public instead of Private. Once I changed it back to Private, the connection went through. Thanks for all your help.

Excellent! And you are welcome.
