We have found that it MIGHT be connected with the MTU size. Our network technicians are diggin' in deeper if it is the cause of this problem.

Well, this network has no proxy, and reaching anything that is not blocked by Ecpat works. I have asked our network gurus to look into the matter. I'll keep you posted.

My colleagues can't connect either. So something in my network is filtering out your addresses (and your only). Time to make a support call, I guess ... But it's really strange that traceroute works.

Can you check calls from 192.36.162.*? That's me. This might be a network thing on my side (at work, so I can't control it), because if I use my phone to connect, it works, but if I switch on wifi on the phone the connection times out. But it's strange that it is only your servers that I fail to connect to. Absolutely everything else works as expected on this work wifi.

Nope. Times out. On all web browsers. All other web traffic working fine.

Shaking this thread a little. Doing a traceroute works fine, but I never gets the site loaded to either of my web browsers (Firefox/Safari/Chrome), "The server is not responding". The web page works fine on my mobile, but not on my computer.

No problem. I undestand the obstacles. It's a "nice to have" function, but only if it can be trusted.

Plus one on this, especially if it will be possible to add the price of electricity to the Energy Meter. If you have electrical heating, the overlay of outdoor temperature and price will help you save money.
