Thought I'd post this here to see if anyone has encountered any issues connecting to their Pangolin VPS while using Tailscale?

I have a Pangolin running on a Racknerd VPS. The system has been solid for nearly 1 year. I use Tailscale to SSH into the VPS to update/backup my services/data.

Recently, I've discovered that I cannot connect to "Pangolin" at "pangolin.mymadeup.domain" from my local devices (PC, Laptop, iMac, iPhone). I simply receive "This site can't be reached."

As soon as I turn off Tailscale, I can reach my pangolin domain and log in without issue.

I am running "Technitium DNS" on two separate machines locally. All my local devices are set to use Technitium for DNS and ad-blocking (works great, mostly).

Tailscale is set to use these same 2 Technitium instances to enable DNS & adblocking on my tailnet network. This setup, again, works great. Except I cannot reach my Pangolin domain while connected to my Tailnet (same result whether I'm connected to Tailscale via my LAN, or if I connect using another network (like cellular network).

I have manipulated the settings within Tailscale without any positive results. I have tried toggling 1) toggling Override DNS Servers, 2) Disabling/enabling MagicDNS, and 3) disabling/enabling HTTPS... still not able to access Pangolin domain while connected to Tailscale.

Ordinarily, this wouldn't be a problem because I could simply turn off Tailscale, but I have come to rely on it for much of my homelab (ad blocking, ease of access, Tailscale SSH, etc.).

Let me know if you've experienced this issue and if you've found a workaround.
Thanks!

I updated my Pangolin instance to v18.0 yesterday and then to v18.1 this AM. I noticed something new that I think may be causing trouble with accessing my self-hosted apps.

In the Public: Resources tab, there is a new icon that shows that the certificates for my subdomains are pending.

If I click on any of my resources to edit them, a new title bar appears indicating that the certificates are pending for that resource.

Can anyone help me understand what is going on? When I check the acme.json file, I can see it was updated today (reboot following Pangolin update).

It appears that this is impacting my ability to reach resources that are directly proxied by Pangolin, i.e.; Pangolin-->Newt-->Nextcloud = Site can't be reached
This also occurs when proxying services locally on the same VPS as Pangolin.

However, most of my resources aren't affected (yet) because I run most of my resources behind SWAG internally, i.e,; Pangolin-->Newt-->SWAG-->Vaultwarden = site reachable

Also, I have configured Pangolin/Traefik to use DNS challenge to pull domain/wildcard certificates.

Let me know if anyone has any ideas why my certs are pending.

Thanks!!!
