Share link doesn't work on my Wifi network

Hello,

when trying to open a share link on my mac it doesn't work on my wifi network

also opening it on my phone with the same wifi doesn't work

it shows the message "Something went wrong."

when trying to use the mobile network, it opens fine.

I did not change anything on my network setting and every other website is opening fine

I just want to copy the css of my work to code it.. are there any alternatives to do so until i get a fix?
