Issue description:

The user tried command

register-fne-server <id>

with the appropriate <id> and got the following error message:

Failed to activate your server
\｛
"key" : "glsErr.connectionFailed",
"message": "Connection to https://license.advantest.com/flexnet/deviceservices failed with exception: exception: error on POST request for \ \"https://license.advantest.com/fL

tion reset; nested exception is javax.net.ssl.SSLException: Connection reset ]*

Background information:

The connection to license.advantest.com with port 443 was not really available, but for the FNE server software it looked like that a connection is possible, therefor it tried and failed.

Solution: Enter the line

0.0.0.0   license.advantest.com

to file /etc/hosts.

Reason for error:
the servers tries to use/exceute a shared library located in the /tmp directory. This is not allowed on the appropriate system. Running executables from /tmp is forbidden by the noexec option in the mount flags: check the /etc/fstab entry which looks like

/dev/mapper/vg00-tmp /tmp ext4 defaults,nodev,nosuid,noexec 1 2

Solution:
Ask IT to remove the noexec option to /tmp in /etc/fstab and remount it with
mount -o remount,exec /tmp
on all affected FNE license servers.

In the FNE log file flexnetls.log you maybe find the following message:
server filter checkout rejection
This message is basically saying the license requested is not available, f.e. for a specific serial number.
This is not an error of the server, its just the way the server returns a request for a license that is not present.

In the FNE log file flexnetls.log you find the following entries:

03:36:16,826 INFO main Starting FlexNet License Server 2019.07 (build 256892)

 Note: you can extract the log file errors with command: showlog-fne-server -2

The error indicates a corrupted TS storage. In order to repair it, do the following:

1. cd /opt/flexnetls/socbu
   
   
2. sudo ./reset-fne-server -force
   
   
3. If there is a failover license server configured you need to run the following command (not as root!) on the primary license server ./fne-failover-setup repair primary <failover_host.domain>
   This will repair the primary license server without touching the secondary license server.

   Note: the repair option is available since June 2020. It is not available if an older FNE/FNX installation script has been used and the SW has not been updated since then. Please check with fne-failover-setup -help if the option is available.
   

4. If the failover server is corrupt, then you need to run the following command (not as root!) on the primary license server (this is not a typo - you need to run it on the primary license server!): fne-failover-setup repair failover <failover_host.domain> 

   Note: The command fne-failover-setup uses ssh/scp and sudo. You may be asked for your password several times.

Note: you can check the help page of fne-failover-setup with: fne-failover-setup -help
