XG115 temporarily unavailable

Hello community,

starting 3 days ago my XG115 was coming unavailable multiple times. It started with 10 hours, then 3, 5 and so on. Today it is unavailable for 14 hours now.

Restarting the XG doesn't solve the problem. My first thought was the internet connection as when the XG comes online again it is sending the mails that the GW was down and got up again.

When I could access it again there was nothing in the log except the GW down and up information.

I'm on vacation so right now I don't have physical access to the firewall but one of my coworkers tried to access the firewall on the internal port and gets an error about a wrong configured TLS setting and the browser is denying the connection.

When it gets online again we can access the XG without any problem.

I am not sure what to do next as a restart doesn't help at all.

Could it be that the firewall is getting attacked by DDOS or something similar and the services are crashing ?

Best regards

Benjamin

Which Firmware are you using?

There are couple of issues in the old firmware, which caused this by having memory leaks in certain modules.

Would suggest to Update to atleast V17.1 MR4 or V17.5

So the device will go offline and online (interfaces are flapping)?

Is it a new Device? REV3? So you could check with HDMI (REV3) or VGA(REV2) the appliance itself.

Unfortunately I won't have physical access before thursday.

The device itself was bought in June. I will then take look.
At the moment it is unavailable for 18 hours now.

Interface lights look normal from the video I've seen.

Puh... Could be some kind of service issue, but most likely a Network issue?

I mean, if you restart, and this does not resolve the issue, could be, the appliance IP(s) are not reachable anymore.

So you would need to check, if something is coming or not. Do you mean the Gateway (WAN) is only offline? Can user access Webadmin from LAN?

From WAN I can't reach anything.

From LAN I get the TLS error when trying to reach the Webadmin.

TLS Error is most likely because the hostname does not match the IP internal or client does not trust the Certificate.

But most likely this error is caused by the Provider or connection WAN to provider. You should contact the provider as well.
