MacOS-specific broken pipe error when trying to connect to OpenVPN server

ms flag

For quick confirmation: this works just fine on a Ubuntu install on the same local network.

I'm trying to connect to an AWS Client VPN endpoint from my MacOS (Monterey) OpenVPN CLI client. The output confirms the UDP local and remote links, pauses, then gives write UDP: Broken Pipe (code=32) errors. I don't believe it's network related (at either my or the AWS end) as the same server is successfully connected to from a Ubuntu box on my local network.

openvpn --version reports: OpenVPN 2.5.5 x86_64-apple-darwin21.1.0 [SSL(OpenSSL)] [LZO] [LZ4] [PKCS11] [MH/RECVDA] [AEAD] built on Dec 15 2021

The client was installed via a standard brew install openvpn

I can't see anything obviously wrong anywhere in the config (or local firewall), nor can I find any common steps that Mac users need to take to get a simple outgoing connection initiated. Can anyone help?

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.
