📝 Describe your problem

The item in each monitor > Edit > General > 'Request Timeout' does not change from previous value
For exampple, even if I change a number other than 16 and click 'Save', the status value is reflected as 16.
I am using the Docker version with the beta tag, but I would like to inquire whether the bug only occurs in that version.

@nowniz, If I’m correct, the minimum values are 20 seconds when setting the following settings: Heartbeat Interval, Heartbeat Retry Interval, and Request Timeout.

@homelab-alpha , The screen above showing the change process from 16s to 12s is an example. In reality, if �I click 'save' with over 20 seconds value has changed more than most values, it's retaining the previous value before keeping it changed.

@nowniz, It seems that a calculation is being performed in the background involving the Heartbeat Interval, Heartbeat Retry, and Request Timeout. When you adjust the Heartbeat Interval, the other two values are also automatically adjusted.

Although the minimum value for both the Heartbeat Interval and Heartbeat Retry is 20 seconds, this does not appear to apply to the Request Timeout.

Based on my testing, it is possible to set the Request Timeout to 12 seconds or lower; however, after saving, it reverts back to 16 seconds. It seems that the minimum value for Request Timeout is 16 seconds.

Personally, I don’t fully understand the logic behind this calculation. Is there a specific reason for setting it lower than 16 seconds?

@homelab-alpha ,
I tried to maintain the settings (12s) from the previous version, version 1.23.11.
As you mentioned, it appears that the 'Request Response' value is determined depending on the 'Heartbeat Interval' value and a certain operation of 'Heartbeat Retry'.

So, isn't it possible to set only the Request Response value separately and separately?

@nowniz, I'm not sure about that. It seems that it's not possible if the other two have a minimum value of 20 seconds.
