Hi Andrew,

Looks like your ssh-agent on pumatest has died.

In `log/suite/log`

```auto
   Permission denied (publickey).
        ERROR: command returns 255: ssh -oBatchMode=yes -oConnectTimeout=10 schn02@login.archer2.ac.uk env CYLC_VERSION=7.8.7 CYLC_UTC=True TZ=UTC bash --login -c ''"'"'exec "$0" "$@"'"'"'' cylc jobs-submit --utc-mode --remote-mode -- ''"'"'$HOME/cylc-run/u-ck651/log/job'"'"'' 18730701T0000Z/coupled/17
2022-04-07T14:28:13Z ERROR - [jobs-submit cmd] cylc jobs-submit --utc-mode --host=login.archer2.ac.uk --user=schn02 --remote-mode -- '$HOME/cylc-run/u-ck651/log/job' 18730701T0000Z/coupled/17

```

When a task fails to submit there is no job.err or job.out file generated hence the cylc GUI error that it can’t find the job.err file.

Cheers,  
Ros.
