Dear all, I have this error: paramiko.ssh\_exception.AuthenticationException: Authentication failed. that pauses all my job without neither submitted to the cluster. I checked my ssh key and it is ok, as well as ‘verdi computer test’, that gives all ok. I tried to restart the daemon, still not able to fix. (The complete error is reported below) Any suggestions? Thanks a lot Best Chiara Cignarella ```auto +-> ERROR at 2024-01-18 11:28:25.003910+01:00 | Traceback (most recent call last): | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/site-packages/aiida/engine/utils.py", line 187, in exponential_backoff_retry | result = await coro() | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/site-packages/aiida/engine/processes/calcjobs/tasks.py", line 86, in do_upload | transport = await cancellable.with_interrupt(request) | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/site-packages/aiida/engine/utils.py", line 94, in with_interrupt | result = await next(wait_iter) | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/asyncio/tasks.py", line 571, in _wait_for_one | return f.result() # May raise f.exception(). | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/asyncio/futures.py", line 201, in result | raise self._exception.with_traceback(self._exception_tb) | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/site-packages/aiida/engine/transports.py", line 89, in do_open | transport.open() | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/site-packages/aiida/transports/plugins/ssh.py", line 498, in open | proxy_client.connect(proxy['host'], **proxy_connargs) | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/site-packages/paramiko/client.py", line 450, in connect | self._auth( | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/site-packages/paramiko/client.py", line 781, in _auth | raise saved_exception | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/site-packages/paramiko/client.py", line 757, in _auth | self._transport.auth_publickey(username, key) | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/site-packages/paramiko/transport.py", line 1635, in auth_publickey | return self.auth_handler.wait_for_response(my_event) | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/site-packages/paramiko/auth_handler.py", line 259, in wait_for_response | raise e | paramiko.ssh_exception.AuthenticationException: Authentication failed. +-> ERROR at 2024-01-18 11:31:35.727007+01:00 | Traceback (most recent call last): | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/site-packages/aiida/engine/utils.py", line 187, in exponential_backoff_retry | result = await coro() | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/site-packages/aiida/engine/processes/calcjobs/tasks.py", line 86, in do_upload | transport = await cancellable.with_interrupt(request) | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/site-packages/aiida/engine/utils.py", line 94, in with_interrupt | result = await next(wait_iter) | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/asyncio/tasks.py", line 571, in _wait_for_one | return f.result() # May raise f.exception(). | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/asyncio/futures.py", line 201, in result | raise self._exception.with_traceback(self._exception_tb) | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/site-packages/aiida/engine/transports.py", line 89, in do_open | transport.open() | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/site-packages/aiida/transports/plugins/ssh.py", line 498, in open | proxy_client.connect(proxy['host'], **proxy_connargs) | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/site-packages/paramiko/client.py", line 450, in connect | self._auth( | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/site-packages/paramiko/client.py", line 781, in _auth | raise saved_exception | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/site-packages/paramiko/client.py", line 757, in _auth | self._transport.auth_publickey(username, key) | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/site-packages/paramiko/transport.py", line 1635, in auth_publickey | return self.auth_handler.wait_for_response(my_event) | File "/home/cignarella/micromamba/envs/aiida-sscha-1d/lib/python3.10/site-packages/paramiko/auth_handler.py", line 259, in wait_for_response | raise e | paramiko.ssh_exception.AuthenticationException: Authentication failed. +-> WARNING at 2024-01-18 11:31:35.742827+01:00 | maximum attempts 5 of calling do_upload, exceeded ``` ---

Hi @ccigna, if `verdi computer test` is good, then you have connection to the remote machine (on CSCS I guess?) If the process is in pause state, you can run `verdi process play -a` to resume all the paused processes.
