It looks like somebody also already opened a PR in phacility/arcanist regarding this issue:

A coworker was running into similar issues internally, and it appeared to be related to https://docs.certifytheweb.com/docs/kb/kb-202109-letsencrypt/<https://docs.certifytheweb.com/docs/kb/kb-202109-letsencrypt/> . He had to update custom.pem inside arcanist/resources/ssl (he copied it over from an internal certificate bundle) ... the README in that directory has more information.

    On both machines, I can go directly to the page. On the windows machine, curl retrieves the page. On the linux machine, I get a similar error:

    ```
    curl https://reviews.llvm.org<https://reviews.llvm.org>
    curl: (60) server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none
    More details here: http://curl.haxx.se/docs/sslcerts.html<http://curl.haxx.se/docs/sslcerts.html>

    curl performs SSL certificate verification by default, using a "bundle"
     of Certificate Authority (CA) public keys (CA certs). If the default
     bundle file isn't adequate, you can specify an alternate file
     using the --cacert option.
    If this HTTPS server uses a certificate signed by a CA represented in
     the bundle, the certificate verification probably failed due to a
     problem with the certificate (it might be expired, or the name might
     not match the domain name in the URL).
    If you'd like to turn off curl's verification of the certificate, use
     the -k (or --insecure) option.
    ```

    If the problem is purely on my end, I suppose I can take it from here. Thanks for the help!

    Thanks,
       Chris Tetreault

    On this machine, does it work when you use a browser?

    What about curl on the command line?
    Try: curl https://reviews.llvm.org/<https://reviews.llvm.org/>

    If curl reproduces the issue, there are many tracing/debug options for curl.

    Also I don't know if you tried the --trace option that arc suggests and if it gave more info?

This usually indicates that the remote host has an SSL certificate for a different domain name than you are connecting with. Make sure the certificate you have installed is signed for the correct domain.

This usually indicates that you are using a self-signed certificate but have not added your CA to the CA bundle. See instructions in "libphutil/resources/ssl/README".
