Hello,

Today I can't connect to Spine with the message "sorry, the server could not be contacted", blablabla.

It seems to be up here :
https://downforeveryoneorjustme.com/esotericsoftware.com

I could use it without any problem yesterday. I checked my firewall, even deactivated it and it doesn't change anything. I did not install, uninstall or update any program these last day. So I post here the log and I can see there is a problem but I need help to understand how to fix it :

Spine Launcher 3.7.81

Windows 10 Home x86 10.0

Thank you for your time and help

I'm actually surprised you managed to use Spine so long! Your launcher is quite out of date, just download it again from your license page, run it, and Spine should resume working like normal! If you still encounter problems let us know.

I do not update it because I use the animations in gamemaker. They only support this version and previous ones so it's unsure if the animations will still work if I update it and I'm not ready to throw away hundred of hours of work...

updating it fixed it, thanks. I still wonder why it was working yesterday but it's fixed anyway
