Thanks for your reply.
I can access the admin interface from other places with other devices.
If I try with my laptop in my office – with different browsers – it does not work. When I try outside the office, same thing. Strange thing is, this is for all my laptops, phone, tablet, that I usually use in the office.
Almost like once you have used a device in my office it can never connect to wp-admin again.
Will try the PHP/server error logs.
Thanks a lot
