Posteo is grey, login not working

Hi collegues,

posteo script is not working anymore.

I will provide a testaccount to XNdevel soon.

Hope, he will find the time to check the problem.

 

This is part of the news from Posteo Website, maybe it helps finding the issue:

"New security technology and additional certificate

Dear Posteo users and interested parties,

We would like to inform you about some new pieces of security technology at Posteo.

We have begun to support “Certificate Transparency” technology. In addition, we started using new technology known as “Certification Authority Authorization (CAA)” and “HTTP Public Key Pinning (HPKP)” a few weeks ago. These further increase the security of Posteo for you.

Nothing changes for you – and you do not need to do anything. In this blog article we merely wish to provide an insight into how we are protecting your data at Posteo using these features."
