Testing the connection using “curl --upload-file /var/log/pihole_debug.log https://tricorder.pi-hole.net:9998” gave the following error:
curl: (60) SSL certificate problem: certificate has expired
More details here: https://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.
Also opening “https://tricorder.pi-hole.net:9998/” in a browser show a warning stating that the certificate expired on august 18, 2019.
