I have been using the Web Previewer and it was working fine. The last days it has been showing me "preview not available" message instead of previewing the files. I didn't change anything. 

I would really appreciate if someone could help me with this.

With best regards,


p.s. I also posted this on the component on Forge but noone answered so I wanted to try again ;)

Hi Iris,

I noticed this question was not answered for years, but for completeness sake to the readers who are facing same issue (last week me ;) ) the reason was nothing changed in my solution but on firewall.

The component uses the public APIs from Google and Microsoft.Firewall rule prevented the component's communication to the APIs. Resulting as "Preview not available".
