letsencrpyt issue on one domain

I've just installed a new Ubuntu 16.04 LTS using the perfect server. After doing this, I started migrating old email accounts and websites across.
Everything appears to be fine except for one domain: https://www.xavaudio.co.uk where the certificate appears to be revoked.
Looking in letsencrypt, it appears to have created it and I can't spot anything wrong, but clearly, the browsers have an issue with it.
I've looked and compared the web configuration to my other sites and can't see anything strange.
Any ideas where to look?
Thanks

 

Works fine here in Chromium and Firefox. Maybe a cache issue on your side?

 

Thanks. Really wierd. I've deleted my cache, cookies, tried private browsing sessions, etc, still a problem. Just tried on my phone which I haven't used before for this site and same problem.

 

It looks fine from my browsers too...

 

OK, this might be related to a DNS issue I appear to have - it's taking ages to update and still points to the old Linode's IP address. Strange how most of them have updated, but some appear stuck.

 

Hi, the only problem i see is part of your website is not secure and use http (example :
http://www.xavaudio.co.uk/wp-content/uploads/xavaudio-background.jpg in your homepage). You must replace this by https://url

 

It seems to be a wordpress website : don't forget to replace all your http://yourwebsite by https://yourwebsite in your mysql database.

 

Thanks Christophe, it's all sorted now

 

Had the same problem =/
Took me a lot of troubleshooting to figure it out..

 

What is the url of your website ?
