Mimosa returning to password page

Dear all,
We have a Mimosa C5C Master and Slave,
Recently, there has been an issue, when I enter the password for the Mimosa, it enters and then quickly goes back to the password page, (in both the master and slave), even though there’s no “wrong password prompt”…
Help!
Thanks.

I would recommend double checking that you do not have duplicated IP addresses, then I would try using a different web browser, clearing your browsing data or running your browser in “incognito or private browsing” mode.
