An error when starting the docker, please can you help ? I about wg-manager HOT 5 CLOSED

I ve installed the docker, and when starting it from portainer throws an error:

Error starting
userland proxy: listen udp
0.0.0.0:51820: bind: address
already in use

Anyone can help with these ? 51820 is the wireguard port, and yes, its in use. But how can i solve this ?

Thanks in advance

Do you have another wireguard instance running in your server??

from wg-manager.

@magefesa I ran into the same thing.
My thinking was that I needed to run wireguard on the docker host.
But you shouldn't do that, Running (starting/stopping) is handled on the container.

from wg-manager.

That port is already being used on your host. Try typing "netstat -tulpn | grep 50802” to see what is using it. Probably another instance of Wireguard as @hsosa88 said

from wg-manager.

Same problem for me:

@mewforest did you check if there is something already running on that port on the host?
