Using HTTPS again!
After a little struggle with our previous ssl certificate provider starSSL, which it seams is not so trusted anymore I had to find an alternative.
Eventually I came across letsencrype which provided me with a valid certificate that is valid for the next three months after which it will have to be renewed.
More about the struggle and the now working solution in a later post.
And just as out of personal satisfaction we now have a A+ rating on SslLab
