Same issue here

I’m experiencing the exact same problem. When I try to add a custom certificate, the Certificates interface freezes or breaks — it stops loading completely afterward.

I tried uploading valid .pem and key files, but after clicking Save the UI hangs and the certificate never appears. Restarting the container or clearing cache doesn’t help.

When I try to upload a custom wildcard certificate, I notice in the logs it does not include a domain name:

id: 12, expires_on: '2026-07-21 23:59:59', domain_names: [ null ]

and upon reloading the certificate page it will go blank due to an error:

Uncaught TypeError: Cannot read properties of null (reading 'includes') at h (DomainsFormatter-DRGLydBn.js:1:109) at ld (index-BBAG1AZl.js:49:48769) at M0 (index-BBAG1AZl.js:49:71656) at nS (index-BBAG1AZl.js:49:82048) at LS (index-BBAG1AZl.js:49:117928) at aI (index-BBAG1AZl.js:49:116966) at tg (index-BBAG1AZl.js:49:116794) at xS (index-BBAG1AZl.js:49:113564) at qS (index-BBAG1AZl.js:49:125603) at Ad (index-BBAG1AZl.js:49:124155)

Here is the relevant code snippet:

import {j as e, d as c, ad as m, c as d} from "./index-BBAG1AZl.js"; const h = ({domain: s, color: n}) => { let a; return s.includes("*") && (a = l => l.preventDefault()), e.jsx("a", { href: http://${s}, target: "_blank", onClick: a, className: d("badge", n ? bg-${n}-lt : null, "domain-name", "me-2"), children: s }, s) }
