The Plume instance is installed on a Debian 9 VPN. It runs fine and federates with no apparent problems.
The error:
503 Remove SSL certificate could not be verified
The SSL certs are properly listed in the Apache2 .vhost file.
I then looked through the Snap directory structure and came across the …/ssl directory which was empty:
writeworks:/snap/plume/148/etc/ssl/certs# ls -la
total 0
drwxr-xr-x 2 root root 3 Dec 2 14:54 .
drwxr-xr-x 4 root root 62 Feb 18 08:58 ..
The problem happens when attempting to like or boost a Plume post to any ActivityPub instance. I’ve tested with Mastodon, Friendlica, SocialHome and of course Plume.
How can I get the Snap install of Plume to use the proper SSL certs. They are Let’s Encrypt certs. Clearly a symbolic link can’t be used with a Snap.
