@JIA YING5EF5 , It has happened to me a couple times and luckily I was able to resolve it. There are multiple reasons this could happen. Please try checking all those.
- Check if your system internet proxies are set right.
- Quit Adobe XD and Sign-out of Adobe CC completely. Log back into Adobe CC. (If you see some issues logging back in , then its something to do with you internet proxies or your network).
- Update your Adobe XD to latest version from Adobe CC.
- If the above 3 steps dont work for you then please check out the entire thread as shared by @italosan in his comment.
Basically if you were able to create the link yesterday and not today, then its not an inherent issue but rahter a connectivity/reachability issue. Hence my solution to test out multiple aspects.
Please let us know if this works.
Thanks, Jose
