Handle self-signed certs?

[SonicMagna]

Not sure if this can be done, but I have a use case where a web page (React app, JavaScript) lists out a few hundred internal servers. The servers all have self-signed certificates. Because the browser intercepts the calls with a security warning, they all appear unreachable. If a user first goes to the site and accepts the security prompt, then afterwards this code works as expected but I'm trying to figure out how to simply indicate on the page if the server is reachable for that user, regardless of any cert issues.
Thoughts?

I don't think that's possible. The browser-version of the reachable check is pretty simple: https://github.com/sindresorhus/is-reachable/blob/main/browser.js

It's also technically not reachable, so the detection is correct.

That's what I was thinking as well. I was just wondering if you had any ideas.
I used the browser version and it works fine, for sites without the cert issue.
Thanks much for responding quickly.
