A problem after power outage

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: nil.fi

I ran this command: rebooted servers concerned after power outage

It produced this output: e.g Chrome says Your connection is not private, … NET::ERR_CERT_COMMON_NAME_INVALID

My web server is (include version):nginx/1.12.2

The operating system my web server runs on is (include version): centos 7.5.1804

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don’t know): yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): no

Strangely a few other domains on the same setup are working fine (e.g. hn-dev.eu). And to clarify, nil.fi used to work before the outage just fine

The cert for nil.fi is good for 2 more months.
Please show the URL and error message you get.


The error comes from the browser, can’t upload the image here but it is a generic chrome error screen of connection not being private.

You can use paste.bin or similar service.

https://nil.fi/, https://apps.nil.fi/ and https://www.nil.fi/ work for me. They’re all using correct certificates.

(https://apps.nil.fi/ just returns a test web page, though.)

I’d double check that you don’t have nil.fi on your computer’s (where your browser is) /etc/hosts file.

Or that you’re on a network with split-horizon DNS for that domain.

What’s IP does your computer show for:

ping nil.fi

Also, are you behind NAT? Because appears to be residential. This could just be a lack of loopback/hairpin NAT.

(For me, they all have the IPv4 address, and no IPv6.)

Yep, the IP is ok.

And now it seems to workwith Vivaldi (not yesterday after the power break happened), so maybe it is just chrome cache issue after all :confused:

I’ll check it further and unless the problem shows it again I just apologize and thank you.

I have it in the hosts file for the internal IP of (front) nginx server, but as I said it worked there before the outage just fine. But my Vivaldi gets it now right, so possibly it is just some Chrome cache issue
