This is a very interesting issue.

If we go back from the member profile we have the error in console:

This is because this request to the member profile is done with topcoder.com domain in the header:

But if we load the WM app directly by the link then there is no CORS error, because the header of the request contains the correct WM domain:

So we have to find out why when we click "back" this request to load member profile is done using topcoder.com domain instead of challenges.topcoder.com.

• Or maybe we can relax the CORS policy of the Member Service?
• Or we can open member profile in a new tab (no "back" button - no problem 😉 )

I can reproduce the same on DEV.

@vikasrohit do you have any ideas?

Strange, but I am not able to reproduce it on production for my user account. And I think we are not requesting with the at CORS header, rather it is a Response header.
In case it is still reproducible by many users, I think best way is no "back" button - no problem 😬

Lets move it out of this bug fix cycle, it does not seems to be appearing frequently and looks like a P4.
