the date can not change after i change some times???

Hi elex123.
I’m sorry, I don’t understand the question.
What “date” are you speaking of?
Are you trying to ask how to change the setting "timeout_retry?

yes, you are right,
Can be modified before but can’t be now!

I can ask you other question????

Did you try to edit it via:
Web GUI > Configuration > Scan Configs > Edit Scan Config > Edit Scanner Preferences ?

Please open new topics for unrelated questions.

But not sucess,
