Good morning, I have a Linksys 1200 and since yesterday I haven't been able to connect and I haven't changed anything, I also downloaded the configuration files again and still nothing, something must have changed?

I am in the same boat, I have a TP-Link C9 v1 that was working fine until last week. It stays Re-connecting, I have tiried multiple changes in the configuration and cannot make it work.

Could anyone be so kind and share a working configuration, please?

The picture in the step 3 of the first post is not showing, maybe is just me.

December 23 2025 this "Re-connecting..." dance started on tomato routers. Now I see it also affected dd-wrt.

Be advised that the servers started pushing IPv6 recently (in the PUSH_REPLY there now is redirect-gateway ipv6). The guide references v4 only, so if v6 is disabled in the system OpenVPN will fail to connect. You must explicitly filter out all pushed IPv6 options, see:

Or adapt the guide to include v6.
