WD Partially Connecting

I am having issues with connecting to my WD HD.

  • I can access it using Network on My Mac however it logs me to guest. I don’t know if there’s content with other username so need to find it

  • Mycloud.com says Can’t connect to my WDMyCloud and couple of trouble shooting steps but none of them work

  • I click on Accepting Device Certificates and it

  • and I am unable to remember that password.

Am I out of luck ?
