Please do not ping community members for non-moderation reasons. Doing so will not solve your issue faster and will make people less likely to want to help you.

Direct connection is work

frigid heath Sep 13, 2024, 11:40 AM

#

And we need much more info

Domain? What are your SSL settings in CF? does your origin have a cert? What are you trying to achieve?

what

crisp tangle Sep 13, 2024, 11:53 AM

It had been working normally, but the domain name expired in August and I forgot to renew it. After renewing it again, there was a problem with the certificate.

It looks like the issue is about the connection between cloudflare and your origin server.
Would you wanna check if you've opened port 443 on your origin server?

why are you doing a subdomain setup

#

you have an apex CNAME record

#

that is a violation of the DNS spec

crisp tangle Sep 13, 2024, 12:52 PM

#

Yes it's open

light venture Sep 13, 2024, 12:54 PM

#

answer my questions

crisp tangle Sep 13, 2024, 12:54 PM

#

you have an apex CNAME record
I don't quite understand

light venture Sep 13, 2024, 12:54 PM

#

why are you doing a subdomain setup

crisp tangle Sep 13, 2024, 12:55 PM

#

Which record are you referring to?

light venture Sep 13, 2024, 12:56 PM

#

go to your overview on cloudflare

#

and send a screenshot of that

#

how do you have a partial setup on a free plan

#

anyway, go to SSL/TLS and check if universal SSL is enabled

frigid heath Sep 13, 2024, 12:59 PM

#

where is the first screenshot from?

light venture Sep 13, 2024, 12:59 PM

#

ssl/tls > edge certificates

#

scroll down

crisp tangle Sep 13, 2024, 1:02 PM

#

Is this the record?

odd marlin Sep 13, 2024, 1:05 PM

#

Well I think "Edge Certificates" should be above this screenshot

crisp tangle Sep 13, 2024, 1:06 PM

#

YES

odd marlin Sep 13, 2024, 1:08 PM

#

Oh right, sorry I missed your first screenshot.

#

To me it's a bit weird because you have subdomains there but not something like example.com and *.example.com

crisp tangle Sep 13, 2024, 1:10 PM

#

I discovered that I didn't add the _acme-challenge record, I'm trying to add

odd marlin Sep 13, 2024, 1:10 PM

#

So you may have found that you don't have any SSL issue with your subdomains like chat.mjj.ee

#

If I understand it correctly, it could be the cert for your chat subdomain. You would either need a separate cert for each subdomain, or you need a wildcard cert.
