Hi,

you need to manually add the certificate authorities from LetsEncrypt to your XG

Had this yesterday. With other CAs of course.

Add the R3 and ISRG Root X1 CA Certs on your XG.

get the certs here:

https://letsencrypt.org/certificates/

tip: remove all blanks or special characters when importing the new CA....

like: ISRGRootX1.pem

or: LetsEncryptR3.pem

And use the same easy names in XG:

In this case, just click on this link and it matters to the firewall?

you need to download these .der or .pem files and upload them on the XG webadmin in certificates > certificate authorities

I imported the 2 files, but in relation to this field do you need to put a key?
Because I imported and still did not load the images.
Or do I need to restart the firewall?

When you are on the internal network and click on accept the laughs it shows this message

Solved, the site is hosted externally, but the problem was that the company's internal dns server was pointing to another dns ip of the site, someone must have changed it and not updated it.
Thank you for your willingness to help.
