I am having issues connecting to wd my cloud device on wd sync using online account mycloud.com. Every time I try to connect it says " The underlying connection was closed; Could not establish trust relationship for the SSL/TLS secure channel."
And I found why this problem happened:
WD Cloud would gave us a certificate with two subdomains:
DNS Name=device3527555-111111111.wd2go.com
DNS Name=device3527555-111111111-local.wd2go.com
one was bound WAN ip, the other was bound LAN IP.
so HTTPS can works well.
but when in LAN, WD sync requested with ip (stupid) :
https://192.168.100.110/api/1.0/rest/eula_acceptance?rest_method=GET
so the problem happened.
