UKLocalGovernment rule broken for Reading
For whatever reason, http://www.reading.gov.uk is not the same as https://www.reading.gov.uk, so the UKLocalGovernment rule blocks access to Reading's website.
I'd suggest this is a defect with the website ;-) feel free to contact them to resolve this. It might even be worth generating a test tool to compare the results of a GET with/without using HTTPS-E rules to find more cases like this.
