Autobackup fails with certificate error for acb.netgate.com

[robhol]

Title says it. New backups fail and old backups not visible. Cert for acb.netggate.com expired april 20th.

Running community edition v 2.7.2.

Can this be fixed?

@robhol

openssl s_client -connect acb.netgate.com:443 -showcerts

or :

....

They all look fine and valid to me.

@Gertjan Thanks for check

However when attempt an automated backup via acb in pfsense webgui it fails with the following error.

Additionally when I inspect the cert via the browser I only see the old cert...

These errors persist after cache and site settings purging in the browser.

Not sure what to do to re-establish connectivity to acb.netgate.com within pfsense. Nor why my browsers do not see the current certs.

Again thanks for assistance.

@robhol

Strange.

No issues what so ever.
Most of the 1+ million pfSense routers use acb at least every day.

I've many lines like this :

What do you see when you execute :

openssl s_client -connect acb.netgate.com:443 -showcerts

(console or SSH access - option 8)

[robhol]

If it was not strange I would not be asking for help.

The response to the openssl query is below.

@robhol

I don't get it.
Your expired *.netgate.com certificate, that's the certificate of 'last year'.
"acb.netgate.com" is "208.123.73.69" for you, right ?
The same *.netgate.com certificate is used for this forum.

[robhol]

Actually, it is not. For me acb.netgate.com is reachable at 208.123.73.69.

Here's a ping from my pfsense box

I see the same thing now.
"208.123.73.212" still uses an old certificate

@stephenw10 : acb.netgate.com, on "208.123.73.212" serves expired domain certificate.
Can you push a button somewhere

@Gertjan

Those results prompted me to look at pfsense's hosts file. That address is hardwired in that file. I will try commenting out and see what happens.

Commenting out the address fails. Apparently the hosts file regenerates on reboot and it contains the wrong address for acb.netgate.com.

This one : /etc/hosts ?

127.0.0.1	localhost localhost.bhf.tld
::1	localhost localhost.bhf.tld
xxxx

The xxx are all the Static DHCP MAC leases (here : at the bottom of : Services > DHCP Server > LAN of every LAN)
and
the unbound domain overrides I've set up. Here : Services > DNS Resolver > General Settings at the bottom.

By default this file contains (24.03 & 2.7.2) just two lines (AFAIK).
Certainly not a

@Gertjan

Problem solved! Mea culpa as you might have suspected.

Earlier this am I determined that host file contained the .212 address and that it was unremovable because the hosts file was regenerated on reboot. That and your last post led me to the DNS resolver and I found that I had put in an override for acb.netgate.com, apparently some time ago when I was having some upgrade issues. Removed the override and all is now well with autoconfig backup.

Thanks for your patience!!
