If URL is not found then restart the current loop

I am currently working with a CSV file, and have 89 loops, I want to create a condition. I will click on a button to go for another webpage and if that webpage does not come then I want to restart only the current loop again(not whole macro)…

Thanks in advance

The question is not well understood, publish the code of the macro you use and also some images because you did not explain yourself well and it is not clear what you want to do.
