hi NCAS CMS,  
happy new year. I am trying to run an lfric branch specific rosestem test and before christmas it has run. Running a new cylc play I now get:

`2025-01-08T14:29:52Z ERROR - Workflow shutting down - Jinja2Error: An error occured while running the command 'ssh puma2.archer2.ac.uk cat /home4/home/n02-puma/mricha/Branches/LFRic/vn1.2_arch2_lfric_chem_b/dependencies.sh' in order to read the dependencies file.`

I change my .ssh/config t include the [puma2.archer2.ac.uk](http://puma2.archer2.ac.uk) in the hostname list and can ssh from ln02 to puma2 and same for [puma2.archer2.ac.uk](http://puma2.archer2.ac.uk) so I am now a bit at a loss what to try next.

any help appreciated, thanks  
mark

I can run that ssh command successfully from ln02 as well.

Hi Mark,

Happy New Year.

ARCHER2 have restarted a couple of system processes on PUMA2 related to login sessions and believe this should be fixed now.

Could you try running the suite again now please and let us know how you get on?

Thanks  
Regards,  
Ros
