This article addresses an issue where SRX devices generate a LICENSE_CALLHOME_FETCH_FAILURE log even though a valid license is installed. The log appears due to the license auto-update configuration, which attempts to connect to the Juniper licensing server using the callhome service.

The vSRX device logs the following message:

license-check[38581]: LICENSE_CALLHOME_FETCH_FAILURE: Failed to fetch license key from https://ae1.juniper.net/junos/key_retrieval url for 163329081000-KrICl serial

Configuration which generates the above log:

set system license autoupdate url https://ae1.juniper.net/junos/key_retrieval

To resolve this issue, you can choose one of the following workarounds:

• Disable the license auto-update feature:
  delete system license autoupdate
• Filter out the log message in the syslog configuration:
  For detailed steps on filtering logs, refer to KB9382 [juniper.net].
• Modify the license renewal interval to reduce log frequency:
  set system license renew interval 336
  This command configures the SRX to attempt license renewal every 14 days instead of daily.
  

By implementing one of these workarounds, you can prevent unnecessary log messages related to license failure
