Can't web logon after OS5 upgrade and 40 sec reset

@TomCarp

Am I using the right web address to remotely access the EX2 (home.mycloud.com)?

No. Home.mycloud.com is for the My Cloud Home device, which is a completely different device than the My Cloud line of devices. To access the My Cloud web portal for remote access one uses:
https://www.mycloud.com/ (select “Sign into My Cloud” on the right)
Or
https://os5.mycloud.com/
