Script to check for new developer versions

RouterOS Scripting
1

Hi, I have created this script to inform me about new testing versions, but sometimes I get an error:

failure: closing connection: <404 Not Found> 159.148.172.226:80 (4)

And sometimes it works fine.

Do you see any error in the code? thanks.

:global prev ""
:local ch [/system package update get channel]
:if ($ch~"stable") do={/system package update set channel=testing}
:local latest [/system package update get latest-version]
:local changeLog ([/tool fetch "http://upgrade.mikrotik.com/routeros/$latest/CHANGELOG" output=user as-value] -> "data")
    
:if ($latest != $prev) do={
    /tool e-mail send to="admin@mail.com" subject="[Router $sysname] New Testing Version" body="Latest testing version: $latest \n\n $changeLog"
    :set prev $latest
    :delay 1s
    /system package update set channel=stable
} else={
    :log info "Testing Info: No new development version. Current: $latest"
}

try requesting 2 times with a delay

:local latest [/system package update get latest-version]
:delay 1
:set latest [/system package update get latest-version]

sometimes it returns empty value or check for empty value

Ok thanks, this way it seems that it has not given error again.
