no outbounds on previously openvpn'd server

in flag

I am running a LXC container that is VPN'd onto another site which was working fine until recently. For some reason, I cannot get any outbound connections when I am not root, with ovpn running or not.

There is no real activity in the syslog. Literally anything that works on the network does not work unless I'm root.

I have tried resetting ufw's rules (ufw reset) and reinstating them, but I still get no luck. As you can see, the DNS resolver still works.

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
