Cannot connect to a certain domain/server

Hi everyone,

It seems like Swisscom is “suddenly” (the change must have happened in the last few weeks as it was working before) and any connection to certain digitalocean domains is blocked.

As a 3d printer I use Lychee for it, and trying to download the new version of it doesn’t work (URL: https://mango-lychee.nyc3.digitaloceanspaces.com/LycheeSlicer-7.0.1.exe)).

I tried with my home internet (swisscom) and telephone (swisscom) to no avail. Then I did LOTS of testing (I’m a Principal Systems Architect) even trying to mimick old TLS and SSL versions, wget, curl, and a long etc… then I used my company phone (Orange) and voilà! It did then work.

So the issue seems to be somehow related to Swisscom itself. If I could get some help please… I do have a small 3D printing business and I NEED this software to work! (I downloaded it over Orange and installed it BUT the application connects to that domain for license verification so it doesn’t work).

Thanks a lot!
