Entering credentials returns error 530,
this is because Aruba has ftp filters based on the IP address,
no problem with adobe muse by entering my IP address,
but with In-browser editing how do I do it?
it only works with the deactivation of filters in time ...
See http://feedback.inbrowserediting.com/#login-help and check the suggestion in section "Why am I getting an error after entering my username and password?". Let us know if that helped.
