Unable to send Push Message to IOS

Hi all, unfortunately I am not able to send push notifications via the dashboard. it shows the following error

verbose: Current clients %d verbose: Current subscriptions %d verbose: REQUEST for [POST] /parse/push: { "data": { "alert": "jujuuu" }, "where": {} } {"body":{"data":{"alert":"jujuuu"},"where":{}},"headers":{"accept":"*/*","accept-encoding":"gzip, deflate, br","accept-language":"de-DE,de;q=0.9","connection":"keep-alive","content-length":"208","content-type":"text/plain","host":"192.168.12.1:1339","origin":"http://192.168.12.1:4040","referer":"http://192.168.12.1:4040/","user-agent":"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/15.0 Safari/605.1.15"},"method":"POST","url":"/parse/push"} verbose: RESPONSE from [POST] /parse/push: { "headers": { "X-Parse-Push-Status-Id": "j48Njcz937" }, "response": { "result": true } } {"result":{"headers":{"X-Parse-Push-Status-Id":"j48Njcz937"},"response":{"result":true}}} verbose: _PushStatus j48Njcz937: sending push to installations with %d batches verbose: Sending push to 1 (node:23221) UnhandledPromiseRejectionWarning: Error: ca md too weak at Object.createSecureContext (_tls_common.js:273:19) at Object.connect (_tls_wrap.js:1593:48) at Object.connect (internal/http2/core.js:3138:22) at /root/node_modules/@parse/node-apn/lib/client.js:122:44 at processTicksAndRejections (internal/process/task_queues.js:97:5) at async Promise.all (index 0) at async Promise.all (index 0) at async Promise.all (index 0) (node:23221) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag --unhandled-rejections=strict(see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 2)

Start at the /parse/push flow and the @parse/node-apn/lib/client.js location shown in the stack trace; investigate the Node TLS "ca md too weak" error while sending the iOS push. Done means the dashboard push completes without the TLS error and the notification is delivered.
