Webmail not accessible

Webmail not accessible

Hello, we have issues accessing webmail.

We are a team of 20, I have two internet connections, with the main one it doesn't work, if I do tethering it does.

Another teammember can't access it all: different device, connection from another place / different internet connection.

I used traceroute for all the three connections:

Tethering connection: working
