Cannot Ping Fortigate Firewall

Tags: #<Tag:0x00007f3b89888ff8>

I recently upgraded Python to version 3.6, and PHP to version 7.4. Since then, LibreNMS has been unable to reach a Fortigate firewall, which it previously had no trouble reaching. How can I troubleshoot?

snmpwalk -v2c -c community works as expected.

Thank you.

Could be possible that you used the Overwritte IP as comment?

Is about this Assigned IP: Corporate Firewall

Thank you for your prompt response! I cleared that field and attempted to rediscover. The device status changed back to “Up” and I’m hopeful the problem is resolved. I’ll mark your reply as the solution if I see that all is well.
