I just recognized, that I get an https - error: "NET::ERR_CERT_COMMON_NAME_INVALID"
within Firefox an chrome,

when surfing to a subdomain on my Server (which uses SNI in addition with a wildcard certificate).


When checking this server with SSL Test everything seems to be OK

--> SSL Server Test: (Powered by Qualys SSL Labs)

Can this be some issue with my WLAN or Router or my connection to my ISP ?

(or DNS ord DNS-cache issue ?)
