I am seeing this same error when running a copy of the software locally. Here is what I'm seeing in the server logs:

I cannot find anywhere in the code why it is trying to go to responsive-web-design-certificate for the current challenge.

This is happening on multiple browsers. Confirmed Safari on Mac and Chromium on Ubuntu.

I am unable to reproduce on local, and the beta monitoring page does not have any such indication, leading me to the understanding that this is not happening on the beta site itself?.

Comments from OP or @tchaffee do not confirm if its the case for the beta site.

If at all this is reproduced at your end on local then this can be isolated to code changes within the last 4 weeks (since last deploy on the beta site), going by the status page.

Looping in contributors who have made commits during the time frame, to the related areas.

@tchaffee Please log out and try signing in to the beta live site and tell if you're facing the same problem as I'm facing.

@raisedadead There's nothing in the console.

@raisedadead @tchaffee @vkWeb I can confirm this and I have a fix for it. I found it yesterday and implamented it in a PR I am working on. I thought it was due to a unique set of circumstances I found myself in. But then I saw this comment from @tchaffee in Contributors chat

I am running fCC on my own server and I have passwordless sign-in with Amazon SES working. But when users sign out and then go back to the site they are getting a redirect loop warning. Looking at the logs the /en/challenges/current-challenge is sending them to /en/challenges/responsive-web-design-certificate/responsive-web-design-certificate. Which doesn't seem right. Any ideas?

I will have a patch submitted shortly

[vkWeb]

@Bouncey Great! I'll be waiting for the fix.
