Somewhere, in a field in cheshire... alright!
Hello

I switched to Windows 10 64 bit a couple of weeks ago and now I can't use the Royal Mail's Online Postage service. I've tried with Internet Explorer, Firefox, Chrome and Edge. They show the Royal Mail homepage but when I try to sign in it just shows 'This Page Can't be Displayed'. On Firefox it shows the message

'Secure Connection Failed

An error occurred during a connection to www.royalmail.com. SSL received a record with an incorrect Message Authentication Code. (Error code: ssl_error_bad_mac_read)

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
Please contact the web site owners to inform them of this problem'.

I've been in touch with Royal Mail but they say they've not had anyone else with this issue and suggested that its to do with Java (I'm running latest version) or the security settings on my computer.

Has anyone had this problem and found a solution please?

Thanks

Iggy
 
The time and date aren't wrong in BIOS or Windows. Is it not strange that whatever it is affects every browser? I've also noticed that google search doesn't work (I get a blank page) when it goes to HTTPS.
 
Thanks KIA, I've tried what you suggested but it's still the same problem. I have ESET NOD32 running.
 
You were right KIA, I uninstalled NOD32 and could use the Royal Mail site no problem. I've re-installed NOD32 and the site doesn't work.
Can I change something in NOD32 to get around the problem?
 
Yes that works, thanks KIA. Should I leave it checked until I need to use the Royal Mail website? Would it be advisable to notify ESET of the problem I've had so they can fix it?
 
Google search seems to be ok now. I'll drop ESET a message and explain what's been happening. Thanks again KIA.
