firebase sometimes Error while making request: timeout of 10000ms exceeded

similar issue Firebase Messaging: app/network-timeout (Error while making request: timeout of 10000ms exceeded) but i didnt solve with anything.

here is my configuration

const options =  {
            priority: "high",
            timeToLive: 60 * 60 * 24
          };
// i have an option like that

const headLine = 'hello' // under 30 characters
const message_notification = {
            notification: {
              title: 'title not long sometimes under 15 - 20 characters',
              body: headLine,
              url: req.body.url,
              // other: 'other data',
              // tag: req.body.tag,
            }
          };
// i use sendToTopic

package.json

"firebase-admin": "^11.0.0",

what should i do ? what best practice to sent a notification ? should i make it queue ? or just make dead lock ( infinity loop ) until success on sent notification ?

sometimes work sometimes timeout like that .

i have already deploy (production) on VPS Server.
