Owncloud client ver3.6.2 on iPad pro cannot connect to owncloud 10 server. “it is not possible to connect to the server at this time”

ios

#1

i have owncloud 10.0.3 ubuntu 17.04 server. I can access it fine from multiple desktops using multiple users thru web browsers and thru the owncloud desktop clients on windows 10.

I have used the iPad client app before without any issues, but after my recent upgrade to owncloud 10 from OC9, and ubuntu 17.04 from 16.04, i am getting this error:

"it is not possible to connect to the server at this time"

But i am connected thru safari and able to view files there. I checked the owncloud.log in the data dir on the server and i find this error for every login attempt i make form the ipad pro, that i cannot begin to understand:
