Hi Diana,
Thanks for sending us the log output. From what I can see, the thrown exception indicates
a connection error that could have been caused by:
- wrong username/password,
- wrong hostname,
- wrong port number.
The thrown exception "omero.ClientError: Obtained null object proxy" indicates that the Ice router isn't able to obtain a proxy from an Ice node.
The method for obtaining a proxy accepts three parameters, from which two are the username and password. This could indicate that
the credentials are wrong or that the Ice router isn't able to connect to the Ice grid node (firewalling issues).
At this moment in time the output of "bin/omero config get" and the full Blitz-0.log would be helpful for further debugging.
Have you tried connecting using Inisght but disabling the connection encryption (padlock icon)?
Another approach worth trying is connecting to the server using the Python mappings (code should be executed on the machine
acting as the server):
$ export PYTHONPATH=$PYTHONPATH:/home/dhughes/apps/OMERO/OMERO.server/lib/python
$ python
>>> import omero
>>> c = omero.client("localhost")
>>> s = c.createSession("<root_username>", "<root_password>")
>>> a = s.getAdminService()
I hope this helps in resolving the issue.
Regards,
Blazej
