Help

Hi @fangq

there is a working certificate. Checked with Chrome / FireFox, all ok. Checked that port via https://check-your-website.server-daten.de/?q=kwafoo.coe.neu.edu%3A7788 - the same.

A valid certificate:

CN=kwafoo.coe.neu.edu
	17.02.2020
	17.05.2020
expires in 90 days	kwafoo.coe.neu.edu - 1 entry

created today.

If you see the error again: Perhaps share a screenshot.
