Web access disappears. Help.

Hello.

Orthanc server is installed on ubuntu 18.04
After some time, access to web access disappears.
I look at the list of open ports, I don’t see the Orthanc server.

pacs@srvpacs:/var/log# netstat -ntulp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 127.0.0.53:53 0.0.0.0:* LISTEN 517/systemd-resolve
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 781/sshd
tcp6 0 0 :::22 :::* LISTEN 781/sshd
udp 0 0 127.0.0.53:53 0.0.0.0:* 517/systemd-resolve
pacs@srvpacs:/var/log#

I restart the server, the ports are listening, the entry through the web appears.

service orthanc restart

pacs@srvpacs:/etc/orthanc# netstat -ntulp
Active Internet connections (only servers)

There are no error or connection information in the Orthanc logs.
There is nothing in the system logs either.

Hi

Have you tried running Orthanc with the --verbose and --trace flags to get more logs?
Also, is actually Orthanc stil running when you are losing the web access?

Kind regards,

Michel
