Try to connect to portal.checkmk.com and get a request error. Is the portal currently down?
http redirects to https where the tcp connect succeeds but then no further response is being received.
It’s back working as far as i can tell.
They must have some good monitoring system in place that quickly detected the outage and notified the sysadmins
made my day
@martin.schwarz You know how they say in German:
“Der Schuster hat immer die schlechtesten Schuhe”
Not true in our case, our admins are top notch
