Hello i'm having an issue when opening Spine. it keeps saying that's unable to ping the server. i saw that there was already a thread about people having this issue, and i've posted there as well, as i've done all the solutions proposed on that thread but i'm still not able to open spine. I have 2 colleges that got spine at the same time as me, however their spine is working fine and mine is not.
here is the most recent log
