<div dir="ltr">Hello, <div><br></div><div>I have recently installed OMERO.server 5.4.9 on an Ubuntu 16.04 system. The server works as intended with the default ports open. OMERO-insight can be used to connect to and administer the server as normal.</div><div><br></div><div>I have also installed OMERO.web separately from OMERO.server in a virtualenv, as described <a href="https://docs.openmicroscopy.org/omero/5.4.9/sysadmins/unix/install-web/walkthrough/omeroweb-install-ubuntu-ice3.6.html">here</a>. I can connect to the OMERO.web login page (my.serverip/omero), but entering a correct username and pass simply reloads the page. If the server is down, then the OMERO.web login page displays the "cannot connect to server"-message. Also, if I enter the wrong password and/or user then the login page displays: "<span style="background-color:rgb(244,245,245);color:rgb(227,100,111);font-family:Helvetica,Arial,sans-serif;font-size:11px;text-align:center">Error: Connection not available, please check your user name and password."</span></div><div><br></div>It seems like OMERO.web is in communication with the OMERO.server, but that something is not configured correctly when going from the login in to the rest of OMERO.web.<div><br></div><div>OMERO.server/bin/omero admin diagnostics:</div><div><br></div><div><div>================================================================================</div><div>OMERO Diagnostics (admin) 5.4.9-ice36-b101</div><div>================================================================================</div><div><br></div><div>Commands:   java -version                  1.8.0     (/usr/bin/java)</div><div>Commands:   python -V                      2.7.12    (/usr/bin/python)</div><div>Commands:   icegridnode --version          3.6.4     (/usr/bin/icegridnode)</div><div>Commands:   icegridadmin --version         3.6.4     (/usr/bin/icegridadmin)</div><div>Commands:   psql --version                 9.6.10    (/usr/bin/psql)</div><div><br></div><div>Server:     icegridnode                    not started</div><div><br></div><div>Log dir:    /home/omero/OMERO.server/var/log exists</div><div>Log files:  Blitz-0.log                    217.0 MB      errors=39   warnings=3111</div><div>Log files:  DropBox.log                    25.0 KB       errors=0    warnings=10</div><div>Log files:  FileServer.log                 3.0 KB</div><div>Log files:  Indexer-0.log                  365.0 KB</div><div>Log files:  MonitorServer.log              13.0 KB</div><div>Log files:  OMEROweb.lock                  0.0 KB</div><div>Log files:  OMEROweb.log                   0.0 KB        errors=0    warnings=1</div><div>Log files:  PixelData-0.log                301.0 KB      errors=42   warnings=4</div><div>Log files:  Processor-0.log                1.0 MB        errors=0    warnings=5</div><div>Log files:  Tables-0.log                   17.0 KB       errors=0    warnings=6</div><div>Log files:  TestDropBox.log                n/a</div><div>Log files:  master.err                     13.0 KB       errors=7    warnings=11</div><div>Log files:  master.out                     0.0 KB</div><div>Log files:  Total size                     218.93 MB</div><div><br></div><div><br></div><div>Environment:OMERO_HOME=(unset)</div><div>Environment:OMERO_NODE=(unset)</div><div>Environment:OMERO_MASTER=(unset)</div><div>Environment:OMERO_USERDIR=(unset)</div><div>Environment:OMERO_TMPDIR=(unset)</div><div>Environment:PATH=/home/omero/bin:/home/omero/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin</div><div>Environment:PYTHONPATH=(unset)</div><div>Environment:ICE_HOME=(unset)</div><div>Environment:LD_LIBRARY_PATH=(unset)</div><div>Environment:DYLD_LIBRARY_PATH=(unset)</div><div><br></div><div>Cannot list deployed applications.</div><div>OMERO data dir:'/tank/OMERO'                  Exists? True      Is writable? True</div><div>OMERO temp dir:'/home/omero/omero/tmp'        Exists? True      Is writable? True   (Size: 0)</div><div><br></div><div>JVM settings: Blitz-${index}                -Xmx7200m -XX:MaxPermSize=1g -XX:+IgnoreUnrecognizedVMOptions</div><div>JVM settings: Indexer-${index}              -Xmx4800m -XX:MaxPermSize=1g -XX:+IgnoreUnrecognizedVMOptions</div><div>JVM settings: PixelData-${index}            -Xmx7200m -XX:MaxPermSize=1g -XX:+IgnoreUnrecognizedVMOptions</div><div>JVM settings: Repository-${index}           -Xmx4800m -XX:MaxPermSize=1g -XX:+IgnoreUnrecognizedVMOptions</div><div><br></div><div>OMERO.py/bin/omero config get:</div><div><br></div><div><div>omero.web.application_server=wsgi-tcp</div><div>omero.web.application_server.max_requests=500</div><div>omero.web.apps=["omero_figure", "omero_iviewer"]</div><div>omero.web.debug=False</div><div>omero.web.middleware=[{"index": 1, "class": "django.middleware.common.BrokenLinkEmailsMiddleware"}, {"index": 2, "class": "django.middleware.common.CommonMiddleware"}, {"index": 3, "class": "django.contrib.sessions.m
