Original GitHub issue: https://github.com/fosrl/pangolin/issues/3093
Describe the Bug
I upgraded from 0.8.1 to 0.8.3 and since upgrading I can no longer connect to my site. The status in the taskbar shows registering. I can see the updated version reflected in the Pangolin dashboard.
Within Preferences -> Status , it shows connected but no sites connected.
Environment
To Reproduce
Attempts to connect to the pangolin site stay stuck at registering. I can re-add the account successfully, but connection never occurs.
Expected Behavior
Expected behavior is the client connects and shows connected in the taskbar section.

Are you behind cf for your control plane at all? asking as they've been having some waf issues lately where it blocks stuff it shouldn't be.
@jelly8perplexed commented on GitHub (May 17, 2026):
Ah, good catch. Yes I am using cloudflare, but in DNS only for any pangolin resources
@jelly8perplexed commented on GitHub (May 27, 2026):
Is there anything that can be done on the cloudflare side or do we just have to wait for an update to their platform?
@jelly8perplexed commented on GitHub (Jun 6, 2026):
Looks like it connects fine through cloudflare, looking at logs on the endpoint.
Hole-punch also works:
It loops here:
Confirmed ports are open on the VPS, nothing changed there. Pangolin setup also hasn't changed.
@AstralDestiny commented on GitHub (Jun 6, 2026):
CF should have fixed it's security rules if you do have it proxied at all right now. You have the wireguard ip set to a non proxied ip right?
@jelly8perplexed commented on GitHub (Jun 6, 2026):
Yes that's correct. It's all dns-only.
I do see logs within pangolin. I tried archiving the client, and then upon reconnecting it shows up in the list but not as an active client. I've fully uninstalled and reinstalled as well.

Although it can connect fine on that port:

oracle or ionos at all?

Negative. I host on digital ocean.
