6.11.1 WIreguard VPN not working anymore

after downgrading to 6.11.0 and removing the part "dev " from the config of the line producing the error vpn works again

Just saw this post, this is affecting me too

 

Have a workaround for this here, but still needs correction

 

This will be fixed in the next release, in the meantime here are the steps to resolve:

just upgraded to 6.11.2 and it’s reverted back to not working again. Would seem it was not fixed?

Open a web terminal and clear out the existing log by typing:

rm /var/log/wg-quick.log

 

Then make a dummy change to your WireGuard tunnel to rewrite it with the new values.

 

Go ahead and start one of the tunnels. It should start fine.

 

If not, in the web terminal run:

cat /var/log/wg-quick.log

and post the results back here.

I'm using unraid 6.11.5 and just upgraded from unraid 6.8.

I had the same problem and I tried the solution in the post you mentioned (regenerate config files by editing network settings and wiregurad settings).

 

Here is my wg-quick.log:

What is the problem you are trying to solve? The log shows that the tunnel started fine.

 

Note that any time you edit the config on the server you also have to update the config on the client.

Sorry for missing the problem description.

 

The problem is, whenever I enable the Wireguard, it will become inactive after a few seconds.

 

 

UPDATE: It works if I create a new tunnel, so I suspect the configuration file is incompatible after system upgrade. e.g. DNS field becomes required after the upgrade.

See if you can recreate wg0 as wg1. If wg1 works, then you can look in the config/wireguard directory on your flash drive and compare wg0.conf to wg1.conf and look for discrepancies. Also compare wg0.cfg and wg1.cfg

 

If you can find a difference (or even if you can't), go ahead and send all the files to me in a DM. Just be sure to delete any Public/Private/Shared keys from the files before sending. 

im on 6.11.5 and i cant seem to get the tunnel working here is the log

 

"wg-quick down wg0
wg-quick: `wg0' is not a WireGuard interface

wg-quick up wg0

the xxx is in place of my actual network ip but in the file it shows correctly.. i cannot get anything to handshake  and not sure whats what as i have  port forwarded and all that fun stuff
