Jmeter Recording Issues for Appian 16.2

Appian URL is not getting recorded in Jmeter under Recording controller.

Ensured its not a regular expression issue by recording other websites. For other websites recording works fine.

For Appian all it records is "Success.txt" with URL as GET http://detectportal.firefox.com/success.txt

Appian version - 16.2

It does not recognize my navigation on Appian URL.  I followed the instructions as per this link

Any suggestions based on previous experience will be highly appreciated.
