OMERO client does not open but indicates automatic shutdown

[albot]

Dear all,

On one of our client computer we have issues to start up insight.
Whenever we try to login insight refuses to start and gives the message that the network is shutdown and the application will automatically be stopped after 2 min (a countdown is started at the same moment).

We do not see this on other computers - could you please elaborate to what web site OMERO insight tries to connect on startup?

The affected computer is not allowed to connect to the internet due to IT policies of the departement. It is only able to access the internal network i.e. it correctly sees the OMERO server.

We are using OMERO 4.4.8.

Thanks for your feedback.

Best regards
Alex

Dear Alex
We have removed any connection to any website in 4.4.8 (linux was the only case we were checking the openmicroscopy website).We check if the network is up using NetworkInterface.
Could you check the version of the client on that computer?
and if possible, give us more detailed information about the set-up so we can try to reproduce the issue.

Thanks
Regards

We have the same problem here with the 4.4.7 version.
Recently, one of our computers (under Windows 7) stopped connecting to OMERO using the ImageJ plugin (in Fiji).
This computer can connect to the server using the Insight stand-alone or even Samba however.
Moreover, it was working last week... And Fiji can connect to the update site (and I tried with the firewall off, so it should not be the problem).

Also, it worked again after one reboot, but stopped after the next...

Dear Pierre,

What is the OMERO server version you are connecting to with the Insight and FiJi clients? It's possible that a version mismatch between the FiJi plugin and the OMERO server might cause problems. Which version of OMERO.insight-ij are you using? If they do mismatch, does updating the plugin version to match the server version help? Do you see any errors logged (see ~/omero/log/omeroinsight.log)?

Regards,
Roger

The OMERO server version is 4.4.7, as is the Fiji client.
The Insight client is older though: 4.4.4.

All I have in the logs is this:

I tried with OMERO.Insight 4.4.7 and I have the same error...
I don't see why Java suddenly reports the network as down...

Ok. It should be the same problem as here:
http://trac.openmicroscopy.org.uk/ome/ticket/11244

[ppouchin]

Nevermind. Apparently, reinstalling the most recent version of Java fixed it...

To follow up, you can now download an updated version of the 4.4.8 clients (4.4.8p1) from https://www.openmicroscopy.org/site/products/omero/downloads which addresses this issue.

Kind regards,
