Kindle for PC

[dpeppere]

Hi, I have had Kindle for PC running fine on a Win 11 desktop using a BT router. I have now changed broadband supplier, and while I can register the Kindle app for PC I can no longer download books. Has anyone seen this before. No error message just doesn't download. I have a case open with Amazon, but the issue does correlate with the change in the router so I am wondering if there isn't some kind of a security setting I don't know about. Has anyone any ideas or seen this before? The Kindle app on my iPad works fine.

@dpeppere Try changing the DNS setting on the router to 1.1.1.1 and 8.8.4.4 , the Vodafone DNS sometimes causes odd problems.

A bit of a drift towards off topic perhaps but I have been having dreadful problems lately with CloudFlare (1.1.1.1 / 1.0.0.1) for which, needless to say, Vodafone was roundly, lengthily and volubly blamed 😁.   
 I changed my  primary DNS from 1.1.1.1 (Cloudflare) to 8.8.8.8 (Google) and the normal blindingly fast  service was immediately restored.

I'd rather not use the Google DNS but I'll leave it set for the time being.

@HappyNomad  Do you have DNSBench from Gibson Research? 

With the exception of my local DNS server on Pi Hole, the following are the fastest DNS servers on my connection;

1.0.0.1             one.one.one.one
1.1.1.1             one.one.one.one
4.2.2.1             a.resolvers.level3.net
4.2.2.3             c.resolvers.level3.net
4.2.2.5             e.resolvers.level3.net
4.2.2.6             f.resolvers.level3.net
8.8.4.4             dns.google
8.8.8.8             dns.google

Haha, I have just run the benchmark again, and naturally the fastest ones have changed. 😄

I don't have DNSBench but I do remember being an almost paranoid user of Gibson's 'Shields Up' back in the day.  😀   I'll have a look at DNSBench but in reality, until this weekend I've not had a speed issue with CloudFlare.  

This issue wasn't one of speed... more a case of nothing at all happening, long long pauses before getting the requested page, endless 'Server has stopped responding' error messages etc.  

Changing to 8.8.8.8 has entirely restored normal service so I am bound to conclude that CloudFlare was the problem which seemed to start on Thursday evening, becoming progressively worse until early this morning when there was more or less nothing at all beyond 'Server has stopped messages'.

If that doesn't work you could also try logging in to the router's gui and disabling IPv6 and IPv6 ULA in >Local Network

Many thanks @Cynric and @Ripshod - I applied both of your suggestions - not a great diagnostics approach, I admit, but I can't see myself using IPv6 any time soon - and its all fine now. Thanks again for your time and support

[dpeppere]

In the end, I couldn't leave it like that, so went back and re-enabled IPv6 - still  OK so seems like it was the DNS. Just in case it's of interest. Thanks again

It was probably being caused by Vodafone's content controls. By not using their DNS you have bypassed them.
