Error 526: Invaild SSL certificate for https://talkstaindcommunity.cf/

Hello, I have a problem with my domain https://talkstaindcommunity.cf/!

The issue:

Please note: I have access to the Cloudflare account associated with the website, so I can perform troubleshooting steps!

So what should I do?

CC: @Neeraj_1

You need a valid certificate on your origin - like a origin certificate.

So check my certificates?

The certificates look like this:

Edge Certificates

Client Certificates

Origin Server

And I don’t see an expired, revoked, or “infected” certificate, so why would I be seeing the error?

2 Likes

Well, the certificate hasn’t expired

And I don’t think it’s self-signed (as the website has loaded successfully before)

And, most importantly: The security setting is Full (Strict)

So why would this issue be occurring?

Update: When running the site through radar.cloudflare.com I see this:

Would either of those certificates trigger a 526 error?

That’s the edge, not your origin.

As the error says, your origin’s certificate has expired.

Pause Cloudflare or set the DNS record to DNS Only if you want to see that certificate.

I’ve paused Cloudflare, how long will it take for Cloudflare to show the expired certificate?

Depends on DNS caching, but that’s the origin.

Btw, WITH Cloudflare PAUSED I CAN see that the certificate has expired!

How do I get a new certificate?

Contact your hosting provider and ask them to renew it or generate an origin CA certificate to install yourself/provide to them.

Do I leave Cloudflare paused?

I’d suggest yes, leave it paused until you get a new SSL certificate (renewed) and confirm your website is working without errors over HTTPS. Upon that, un-pause it and double-check if everything works smoothly as it should and was :wink:

Well there goes the ICANN method of figuring that out

How else might I find out who the hosting provider is?

My best guess, checking by the DNS records at the DNS tab of Cloudflare dashboard for your domain name, the IP address should provide you some information to whom does it belong and who might provide web hosting services to you? :thinking:

Or you’ve used Cloudflare Workers only?

So try to put those in ICANN?
