clarify what do you mean by this:

Direct from link > is working but > behind mikrotik > is not any more. Nothing was change!

Also, what is the exact error message in the browser, when the site doesn’t open ?

It was a restriction at destination server for my range of ips. I informed the host company about that. Soon it is going to be fixed.

Direct from the internet link. From the fiber router but it was tested with other range of ips. That is why worked.

Thanks for you attention!
