Error install extension

Hi, i try to install in a docker container v1.19 the tabnine extension,

and on the logs (docker logs mycontainer) i got the next error (after click Install button ± 1 mins):

root INFO [tabnine.tabnine-vscode]: trying to resolve latest version...
root ERROR Failed to resolve plugins from 'vscode:extension/tabnine.tabnine-vscode' Error: getaddrinfo EAI_AGAIN
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:66:26)

any idea how to fix it?
