Using fiddler as reverse proxy get this "This web property is not accessible via this address"

[chen]

HI:

I'm try to use fiddler as reverse proxy ,and i Write a FiddlerScript Rule like this

if (oSession.host.toLowerCase() == "192.168.5.201:8889") oSession.host = "pubs.acs.org";

then i try access https://192.168.5.201:8889 , I get this:

 i know this is because cloudflare detective it as a ddos attack.

Does it possible to solve this problem?

This error seems like a generic one from Cloudflare and could be caused by various reasons. One thing you can try is to turn on Ignore Server Certificate Errors option from Tools -> Options -> HTTPS. Then save the settings and restart Fiddler Classic.

Another option is to modify your hosts file directly instead of using FiddlerScript to modify the requests - just use Tools -> HOSTS, then load the Windows Hosts file and add mapping of your ip and the host you need. 

If none of the above works, there are various resources for similar errors in the CloudFlare community and suggestions how to fix them, for example:
