Host OS

CPU arch

x86_64

VPN service provider

IVPN

v3 to latest

What's the problem 🤔

Shortly after the close of https://github.com/qdm12/gluetun/issues/2217 I found root cause. I have a wrapper/manager process which makes use of the Control Server. This was previously using the /v1/openvpn/status endpoint against a Wireguard configuration. While the documentation does note this is for OpenVPN this functioned fine up to v3 (or later). I've since updated to using /v1/updater/status instead.

Nonetheless, this results in crashing the Gluetun client and attempted restarts as shown in the log below as well as previous bug report.

curl -X PUT localhost:8000/v1/openvpn/status -H "Content-Type: application/json" -d '{"status":"running"}'
{"outcome":"crashed"}
