[ovirt-users] unable to upload disk images after upgrade to 4.3.3 -- ticket failures

Previously I had issues with the upgrades to 4.3.3 failing because of "stale" image transfer data, so I removed it from the database using the info given here on the mailing list and was able to complete the oVirt node and engine upgrades. Now I have a new problem. I can't upload a disk image anymore, which used to work. "test connection" returns success. In the dashboard Storage/Disks view, it starts and then stops with "paused by system" I tried pointing it at another node, same problem. I tried restarting services ovirt-imageio-proxy on engine and ovirt-imageio-daemon on the node, same failure. in the dashboard events when trying to upload disk I get this error Transfer was stopped by system. Reason: failed to add image ticket to ovirt-imageio-proxy. or when trying to resume transfer "paused by system" giving it the local path again. Transfer was stopped by system. Reason: failure in transfer image ticket renewal. I'm not sure what logs I should be looking deeper into.. Here's what the database says engine=# select * from image_transfers; -[ RECORD 1 ]-------------+------------------------------------- command_id | 59dce2b1-f8ba-44dd-9df9-c6e39773a3f9 command_type | 1024 phase | 4 last_updated | 2019-04-23 12:22:25.098-04 message | Uploading from byte 0 vds_id | disk_id | 6693d5ac-d3eb-43d7-9abe-97c5197efc23 imaged_ticket_id | proxy_uri | signed_ticket | bytes_sent | 0 bytes_total | 1996488704 type | 2 active | f daemon_uri | client_inactivity_timeout | 60 -[ RECORD 2 ]-------------+------------------------------------- command_id | 16898219-be5b-4826-8f20-3355fa47272a command_type | 1024 phase | 4 last_updated | 2019-04-23 16:15:34.591-04 message | Uploading from byte 0 vds_id | disk_id | 3b8e3053-bfe4-49d3-abd2-5452b1674400 imaged_ticket_id | proxy_uri | signed_ticket | bytes_sent | 0 bytes_total | 1998585856 type | 2 active | f daemon_uri | client_inactivity_timeout | 60 I really need the image uploading to work.
