Website verificative does not work when one of the 2 URLs return a 403

## steps to reproduce
- add the proof to /keybase.txt
- return HTTP status code 403 for a request to /.well-known/keybase.txt
## expected result
- verification is working
## actual result
- verification is not working
- the webserver logs a request to /.well-known/keybase.txt and returns a 403 error
- the webserver DOES NOT log a request to /keybase.txt
- after changing the webserver to return a 404 for /.well-known/\* ... it is working fine

Reproduce the verification flow with proof content at /keybase.txt while /.well-known/keybase.txt returns 403, then compare it with a 404 response. Inspect the verification entry point that requests these two URLs; done means verification succeeds and the webserver logs requests to both paths when either URL returns 403.
