ZeroSSL problem with CRL

RouterOS
1

Hi,

I created a certificate on ZeroSSL for my routerboard's https interface.
Everything seems to be working fine, but I found an error in the log:

So I checked the certificates and found, on CRL tab, an error:

"Status: DI"
"URL=http://cri.usertrust.com/USERTrustRSACertificationAuthority.crl"
"Certificate: Zerossl_ca_bundle.crt_0"

How can I fix Status?

On a pc. Open your web browser and paste the http url in the address bar.

http://cri.usertrust.com/USERTrustRSACertificationAuthority.crl

Does the crl file download?

If so, try rebooting the router.

Oh you just want an answer… That url is no longer valid. I don’t know why ZeroSSL is using an expired USER Trust Certificate and cross-signing it. If the Zero SSL CA bundle it working. Just disregard the Invalid crl error and just remove it from the CRL store.

Done

Thank you,
I'm amazed by what you're telling me. Next week I'll do as you suggested: I'll look for a link that hasn't expired.
Thank you so much.
