I'm trying to run BOINC (v7.6.31+dfsg-6ubuntu1) on my VPN digitalocean droplet running Ubuntu 16.04. The droplet is also my VPN server, and was created & configured automatically with the Streisand VPN script. (git is here: github.com/StreisandEffect/streisand )

I log in,

sudo apt install boinc-client
reboot

boinccmd --get_state
Operation failed: read() failed

Every command results in "Operation failed: read() failed"

In addition to defaults, I've turned on the following log flags:
<task_debug/>
<gui_rpc_debug/>
<slot_debug/>

/var/log/boincerr.log
dir_open: Could not open directory 'slots' from '/var/lib/boinc-client'.


Creating /var/lib/boinc-client/slots makes that error message go away, but doesn't fix "Operation failed: read() failed"

adding 2.0.177.102 to gui_rpc_auth.cfg makes that error message go away, but doesn't fix "Operation failed: read() failed"'

any ideas? I assume the VPN script has done something that breaks BOINC, but I don't know what. I really want to run BOINC on my VPN :(

According to Streisand readme it installs UFW. Maybe UFW blocks BOINC's communications too.
