Hi xzmeng,
Hmm, to confirm, does this issue happen in all browsers or just Chrome? Likewise, does it happen with all files or one specific file? Are you able to view the prototype if you generate local HTML or publish to Axure Share?
When you click the preview button, Axure RP generates a preview on localhost at IP 127.0.0.1. If the issue happens for all files in either one or all browsers, then you’ll want to ensure that nothing on your machine or network would be blocking Axure RP from generating that preview, and that access is allowed to 127.0.0.1. If you’re on a Mac then the proxy configuration is handled in “System Preferences > Network > Advanced > Proxies”, where there is a text field titled “Bypass proxy settings for these Hosts & Domains”: you’ll want to ensure that *.local, localhost, 127.0.0.1
is included in that area for each proxy that you have.
Hopefully that helps, and generating HTML helps as a workaround in the meantime.
