Error Sending Checkmk notifications via Telegram

CMK version: CheckMK 2.1
OS version: CentOS 7
Currently I am having problem sending checkmk notification to telegram, the message is sent back to telegram 2 times in a row with identical content for 1 alert status. How can this not happen?

I have referenced the following Script and instructions: Sending Checkmk notifications via Telegram | Checkmk

Hi.
I think in your notification rule you use a contact group with two member. Please use only one contact in the rule like automation or cmkuser. Than you will have only one alert.

Thank you very much for your feedback, Now the error has been fixed…

There is a problem that needs to be fixed, the SNMP response time is too long.

Here is a message sent to telegram

"[snmp] SNMP Error on x.x.x.x: Timeout: No Response from x.x.x.x (Exit-Code: 1)(!!), Got no information from host(!!), execution time 18.9 sec .

How does this not happen? Is there any way to increase the response time from the server
