on ceph logs i see

 mon.0@0(leader).auth v227 client did not provide supported auth type

tested again with clean install of 4.4 and updated to current - problem is there, can't connect storage.
clean install of 5.0 and updated to current - connects to ceph without problem.

what's your ceph version on the client side? "ceph --version" or "rbd --version" should tell you.

client 4.4
ceph version 0.80.7 (6c0127fcb58008793d3c8b62d925bc91963672a3)

on 5.0
ceph version 12.0.3 (26cbb7ec2e7864aaa43528631331338f1ea55775)

I'd recommend installing the Jewel packages using "pveceph install --version jewel" on the client side. the stock Debian Jessie ones (which you have installed) are rather old (Firefly, which is out of support upstream since 2016 already, because it is the old old LTS release..).

Installing jewel do the trick, 4.4 is connecting to ceph again.
Thank you.
