Hi, I have a problem using the upload feature in Ovirt GUI (Storage/Disks -> Upload button) that maybe you could help me resolve. The problem is with the transfer that starts... and stops abruptly. What's more, logs (below) do not register any errors. I am using a hosted-engine in a brand new Ovirt 4.5.4 environment with Ovirt nodes running CentOS 8 Stream. I have uploaded the CA certificate to the browser (Chrome, Edge). Thank you and best wishes, Adam Logs: /var/log/ovirt-imageio/daemon.log 2023-03-15 08:51:17,123 INFO (Thread-25) [http] OPEN connection=25 client=local 2023-03-15 08:51:17,125 INFO (Thread-25) [tickets] [local] ADD transfer={'dirty': False, 'ops': ['write'], 'size': 160432128, 'sparse': True, 'inactivity_timeout': 60, 'transfer_id': '32a96cf6-a0d9-4e85-b80b-034a16a9214b', 'uuid': 'fc5acb59-e8a4-4cbf-bc55-d115aeb760b9', 'timeout': 300, 'url': 'nbd:unix:/run/vdsm/nbd/32a96cf6-a0d9-4e85-b80b-034a16a9214b.sock'} 2023-03-15 08:51:17,127 INFO (Thread-25) [http] CLOSE connection=25 client=local [connection 1 ops, 0.002591 s] [dispatch 1 ops, 0.001178 s] 2023-03-15 08:51:19,440 INFO (Thread-26) [http] OPEN connection=26 client=local 2023-03-15 08:51:19,442 INFO (Thread-26) [http] CLOSE connection=26 client=local [connection 1 ops, 0.001493 s] [dispatch 1 ops, 0.000457 s] (..) 2023-03-15 08:52:21,808 INFO (Thread-33) [http] OPEN connection=33 client=local 2023-03-15 08:52:21,809 INFO (Thread-33) [tickets] [local] EXTEND timeout=300 transfer=32a96cf6-a0d9-4e85-b80b-034a16a9214b 2023-03-15 08:52:21,810 INFO (Thread-33) [http] CLOSE connection=33 client=local [connection 1 ops, 0.001537 s] [dispatch 1 ops, 0.000518 s] /var/log/vdsm/vdsm.log 2023-03-15 08:51:16,810+0000 INFO (jsonrpc/5) [vdsm.api] START start_nbd_server(server_id='32a96cf6-a0d9-4e85-b80b-034a16a9214b', config={'detect_zeroes': True, 'discard': True, 'readonly': False, 'bitmap': None, 'sd_id': 'd3896a51-efde-4723-875f-bdc4c737d0d3', 'img_id': '4fbae53f-2f12-4e46-b54f-3ca09fb00755', 'vol_id': '104ea438-49d1-465e-a489-0695f100d325', 'backing_chain': True}) from=::ffff:[IPV4_NUMBER],41446, flow_id=cdd21264-4021-4ee9-aac1-aefe6f244bb1, task_id=0dea4f64-e790-49fe-bc0d-1f40e6f31610 (api:31) 2023-03-15 08:51:16,823+0000 INFO (jsonrpc/5) [storage.nbd] Starting transient service vdsm-nbd-32a96cf6-a0d9-4e85-b80b-034a16a9214b.service, serving /rhev/data-center/mnt/glusterSD/[HOSTNAME]:_ovirt-engine/d3896a51-efde-4723-875f-bdc4c737d0d3/images/4fbae53f-2f12-4e46-b54f-3ca09fb00755/104ea438-49d1-465e-a489-0695f100d325 via unix socket /run/vdsm/nbd/32a96cf6-a0d9-4e85-b80b-034a16a9214b.sock (nbd:138) 2023-03-15 08:51:16,881+0000 INFO (jsonrpc/5) [vdsm.api] FINISH start_nbd_server return={'result': 'nbd:unix:/run/vdsm/nbd/32a96cf6-a0d9-4e85-b80b-034a16a9214b.sock'} from=::ffff:[IPV4],41446, flow_id=cdd21264-4021-4ee9-aac1-aefe6f244bb1, task_id=0dea4f64-e790-49fe-bc0d-1f40e6f31610 (api:37) 2023-03-15 08:51:17,121+0000 INFO (jsonrpc/1) [vdsm.api] START add_image_ticket(ticket={'dirty': False, 'ops': ['write'], 'size': 160432128, 'sparse': True, 'inactivity_timeout': 60, 'transfer_id': '32a96cf6-a0d9-4e85-b80b-034a16a9214b', 'uuid': 'fc5acb59-e8a4-4cbf-bc55-d115aeb760b9', 'timeout': 300, 'url': 'nbd:unix:/run/vdsm/nbd/32a96cf6-a0d9-4e85-b80b-034a16a9214b.sock'}) from=::ffff:[IPV4_NUMBER],41446, flow_id=cdd21264-4021-4ee9-aac1-aefe6f244bb1, task_id=10f6ed38-2135-4c06-a948-af70af88f743 (api:31)
