I have faced this error message while the Goto opener launched at all browsers.
Try delete all installation & reset IE & check firewall, nothing changed.
Need find what is the so call "technical difficulties".
The opener is working fine at other company PCs.
@lhlSteven When you log into your online account at gotomeeting.com, can you check your personal settings to include both a First and Last name with no spaces in either?
Sir, thanks for your support, but I don't understand, this opener crashed during we start a meeting test, and I don't know where to check the personal setting in gotomeeting.com , we are group user and we start meeting by our internal mail notification as always.
If this behavior exhibits itself on different devices, then it could be a known issue having to do with the name placement. You can check this through gotomeeting.com : https://support.goto.com/article/g2w010006
