Thanks for the reply ola
I did have 1.4 cos I installed using >=1.9.3 (as in docs)

Corrected that and now have
pip freeze | grep gunicorn
gunicorn==19.3.0

But now get this

[NOT STARTED]

Cannot find any processes – like status so I assume it starts and dies immediately??

Shaun

Hi Shaun

Which gunicorn version you have installed?

It has to be 19.3+

you can check by `pip freeze | grep gunicorn`

With the great support of this list and the documentation we have our install of omero up and runnign and can connect with clients not a problem

However the web side does not seem to want to start (see below)

Could anyone suggest where to look to do further debugging – the log at var/log/OMEROweb.log
Just yields a django deprecation warning

OMERO.web status... [NOT STARTED]

We are using nginx – it is running OK – but of course complains about upstream server not being available.

I have turned off (temporarily SELinux and Firewall)

Appreciate any further advice anyone can offer

Shaun
