Connection to telegrab-bridge via nginx proxy - incorrect config

[eking-go]

As I realize, it is there: https://github.com/spantaleev/matrix-docker-ansible-deploy/blob/master/roles/matrix-nginx-proxy/templates/nginx/conf.d/matrix-domain.conf.j2#L119

Now generated configuration looks like:

location /prefix {
                resolver 127.0.0.11 valid=5s;
        set $backend "matrix-mautrix-telegram:8080";
        proxy_pass http://$backend;
}

But have to be like:

location ~ /prefix/(.*) {
                resolver 127.0.0.11 valid=5s;
        set $backend "matrix-mautrix-telegram:8080";
        proxy_pass http://$backend/$1;
}

Then queries to provisioner will pass without prefix:

 curl https://matrix.domain.com/prefix/_matrix/provision/v1/bridge
{"relaybot_username": null}

That inside of container of provisioner looks like (so, inside of container it do not have prefix, and nginx do not have to proxy query with prefix)

$ curl http://172.18.0.16:8080/_matrix/provision/v1/bridge
{"relaybot_username": null}
