Comment:

 Hi @distante and welcome to Trac.

 I've just tested this, and I'm not experiencing any issues.
 Getting `ERR_CONNECTION_RESET` suggests to me that there's a security
 module on your host in play - mod_security or similar which is blocking
 the request. Usually mod_security would trigger a 404/403 error, however
 some network-based blockers may simply drop the connection, which would
 cause that error message.

 I'd suggest contacting your host or trying to reproduce it on another
 hosting environment to determine if it's host specific.
