Hey folks,

I just want to call attention to the fact that we'll be doing system updates tonight, and is in the list of systems that will see service interruptions during the maintenance window.

Hello Forest, still has TLS 1.0 enabled, and no changes were made to openvpn on that host last night (it was just one of the few hundred or so servers that was rebooted for kernel updates).

I'm not sure you're running into the same issue as I see you were able to auth, set up a control channel, then a data channel before the following:

SIGTERM[soft,remote-exit] received, client-instance exiting.

The first attempts I saw from you this morning were around 9am though, so after this message was posted. Were you trying from another device and succeeded? I do see several more attempts on the production server ( but just the one on beta.

Thanks for the info, Justin.

The successes you saw in the logs were probably me connecting from an independent computer while troubleshooting the problem.

Turns out my router reverted when it couldn't reach beta.vpn for a while (I had forgotten I still had that fallback in place), and that's where it was choking on the TLS handshake. Fixed now.

hi Sonic folks, any chance of ipv6 support for the VPN?

I haven't been able to connect to the OpenVPN service for some time through the website or the client. I can login to but can't connect, and the client won't connect either. Is it just me?

Same problem. Firefox and Safari.

I get:

Unexpected error:

DNS lookup failed on host u’’: [Errno 8] nodename nor servname provided, or not known

If that error is verbatim, it looks like you've got u' in front of the hostname in a config file?

u'This is also' the way python 2.x represents unicode strings. If ankh is using an openvpn front-end written in python, the extra u and ' could be a red herring, or it could be that the string is being passed between components incorrectly, or maybe an ancient version of python is being used to run code that assumes a newer version?

I'm using the Mac client from ... loads.html
and the config file I get from Sonic's vpn page. Nothing fiddled with on my end.
