The Kiwi at kiwisdr.jks.com:8074 is running a beta test version of the software.
Please try connecting and see if you find any problems. Sometimes users experience problems that we don't see during development, probably due to differences in network environment, browser issues etc.
Please try accessing the admin page at kiwisdr.jks.com:8074/admin
Please let us know if this is still occurring for you.
Thanks very much!
