sorry but we couldn't connect to our servers

Hey i have this very annoying issue and i rly need a fix.

This issue happens only to me not to my friend. I am on vacation now and since i use a other network (due vacation) this error appears.

What i expected: The MC servers are down. So i checked up if they are rly down and it said they are on. So i decided to ask my friend if MC works for him. So he said yes it works. This made me confused.

What i tried: Updating/Reinstalling java
Removing minecraft folder
Setting up time/clock

I still fail

If anyone can help me i would thank him allot

Here is a screen shot of the issue:
