The server does not have working IPv4

Alpha · June 8, 2023, 11:50pm

Hardware: VPS
YunoHost version: 11.1.20 (stable).
I have access to my server: SSH | direct access via keyboard / screen

Description of my issue

Running 11.1.20 (stable) and suddenly it says I don’t have IPv4 connection. A records and DNS settings are correct. All services running as they should. I can SSH in and perform apt update, no problem. I can curl https://icanhazip.com and it reports correct IP. I have obviously restarted the machine, restarted the services.

Diagnosis reports " The server does not have working IPv4." But DNS records, Ports exposure, Web, Email, Services status check, System resources, System configurations and Applications are all green and functional.

Does the issue persist if you force re-run the diagnosis …?

Yes. The server is not reachable from outside LAN.

I can curl https://icanhazip.com and get my IP back, but now even apt update or wget doesn’t work. Very strange. I’ve tried looking at ports and firewall. I can’t figure it out.

So if it “doesn’t work” then what happens then …

Wget returns:

curl https://icanhazip.com returns correct IP.

Aleks · June 11, 2023, 5:18pm

Then no idea what’s happening, that doesn’t seem related to YunoHost, that seems related to your ISP/VPS provider

Alpha · June 11, 2023, 5:23pm

Perhaps. Even so, it would be great to have ideas to troubleshoot this.

FYI with http://ipv4.download.thinkbroadband.com/20MB.zip:

I’m getting a Gateway Timeout from my browser
wget or curl work fine
