I've installed NEMS 1.5 for Raspberry Pi 3B.

When connecting to the dashboard, it says:
Warning: NEMS can't connect to the update servers. Please make sure Internet is properly configured for your NEMS server.

There are no Internet connectivity issues as I'm able to connect to both the Dashboard webpage as well as via SSH from the Internet.

Appreciate some help in troubleshooting this issue

[CyberDaeng]

Yes, its also happening with me. Install NEMS 2 days ago and still there till now.

What is the full output when you manually run:

Code:

sudo nems-update

Also, where are each of you geographically situated?

[alexander.hagen]

Here’s the full output. My location is Singapore.

Running updates and fixes... Internet is offline. NEMS needs Internet connectivity.


Done.

Hmm, is there anything out of the ordinary about your Internet connection? For example, a proxy?

What is the output of this command?

Code:

ping -q -w 1 -c 1 github.com

[CyberDaeng]

For my side, I dont use any firewall or proxy.

cyberdaeng@nems:~ $ ping -q -w 1 -c 1 github.com
PING github.com (52.74.223.119) 56(84) bytes of data.

--- github.com ping statistics ---
1 packets transmitted, 0 received, 100% packet loss, time 0ms

[CyberDaeng]

I try ping from my PC, and its RTO as well.

C:\Users\Hernan Halim>ping github.com

Pinging github.com [13.229.188.59] with 32 bytes of data:
Request timed out.

Ping statistics for 13.229.188.59:

[CyberDaeng]

But I can open github.com website just fine...

Here's the output from the ping to github.com

snmp@NEMS:~ $ ping -q -w 1 -c 1 github.com
PING github.com (13.229.188.59) 56(84) bytes of data.

--- github.com ping statistics ---
1 packets transmitted, 0 received, 100% packet loss, time 0ms

I've also tried pinging from my router, and from another raspberry pi on the same LAN, all failing. I can open github.com in the browser though. I also pinged the same IP from https://ping.eu/ping, which also fails, so it seems github.com does not respond to ping, at least not in Asia.

I've also used https://ping.eu/ping to ping github.com, which resolves to a different IP and does work.

--- PING github.com (140.82.118.4) 56(84) bytes of data. ---
64 bytes from 140.82.118.4: icmp_seq=1 ttl=58 time=12.3 ms

64 bytes from 140.82.118.4: icmp_seq=4 ttl=58 time=12.2 ms

Using the same IP on the raspberry pi with NEMS also works fine.

snmp@NEMS:~ $ ping -q -w 1 -c 1 140.82.118.4
PING 140.82.118.4 (140.82.118.4) 56(84) bytes of data.

rtt min/avg/max/mdev = 187.690/187.690/187.690/0.000 ms

My internet connection is ordinary. It has a cable modem from my ISP, an ASUS AC87U router with MerlinWRT and the raspberry Pi is plugged into LAN4. There's no proxy. Firewall and DoD protection for inbound traffic is On (default).
