NOOB........ACME / Let's encrypt / OPNsense reboot.

[julcol]

Hi,

I have a fresh 25.2 instalation running as VM in Proxmox. I have pi-hole in a separate VM

I have open WAN to allow 80/443 from want to my opnsense ip instance.
I have created forwarding rules to redirect 80/443 traffic from wan to my opnsense server.
I have dynamic IP address, currently ddns via AWS Route53 via a hosted zone.
Wireward works perfectly.

Using the plugin

I have enabled the plugin
I have created an account
I have created a challenge  HTTP01 a per multiple suggestions due to DNS on pi-hole. I have set up HTTP Service to automatic port forward. Interface is WAN

I create certificate common name --> my domain in route53, accme account --> let's encrypt

I get this eventually in ACME Log

Any  hints how can I overcome this problems ?

After doing this, internet connectivity fails and I have to reboot opnsense......pretty bad actually.

Thanks
