Why the error message: site cant be reached the connection was reset?

[MarkLynt]

I have a new phone s9 and im having connection problems when I access to certain websites only (porn/nudes content). Any browser let me access to those sites, I have tried Samsung Internet, chrome and Incognito! When i share the connection with other devices such as laptops, through Hotspot, I experience the same problem. The error message is "the site cant be reached the connection was reset".

I tried to reset data on the applications and settings, my data save is off and all the settings seem alright.

What else do you suggest?

Thank you!
