Hi Guy's, I might have an idea where the issues i am facing come from.
Does cura start with some network checks or connections to the internet?
Thing is that yesterday evening i noticed i couldn't use the windows store app, also Edge didn't work, They where saying i had no network connection to the internet. I wikr in the network industy so i knew with 100% certainty that i do had a valid and stable internet connection. This seems weird as i now had 3 applications that had issues while others just work fine. I normally don't use Edge or the Store so i didn't knew when these issues started. I figured out that enabling the IPv6 network stack solved the Edge and Store issues, wich is weird as i don't have a IPv6 network in place and my internet provider only supports v4. Then i found this -> https://betanews.com/2018/10/05/windows-10-october-2018-update-breaks-microsoft-edge/
Multiple applications seem to suffer from this windows 10 bug, could Cura be one of them? I've started Cura succesfully ever since i enabled IPv6.
I haven't encountered startup issues on Cura 3.4.1 with this windows 10 build.
I hope this helps and not further confuses things as it confuses me.
