Possible SIP bug when used with OpenSprinkler App

[jgmtfia]

Hello.  I have a open sprinkler system with an expander board.  I upgraded to Debian 10.3 and the latest git image of sip.  When I try to connect manually from the OpenSprinkler android app I see the following on the python console:

Code:

::ffff:192.168.5.157:43186 - - [19/Mar/2020 18:20:22] "HTTP/1.1 GET /jp"- 303 See Other
::ffff:192.168.5.157:43186 - - [19/Mar/2020 18:20:22] "HTTP/1.1 GET /login" - 200 OK
::ffff:192.168.5.157:43186 - - [19/Mar/2020 18:20:22] "HTTP/1.1 GET /jp"- 303 See Other

::ffff:192.168.5.157:43186 - - [19/Mar/2020 18:20:22] "HTTP/1.1 GET /jp"- 303 See Other
::ffff:192.168.5.157:43186 - - [19/Mar/2020 18:20:22] "HTTP/1.1 GET /login" - 200 OK
::ffff:192.168.5.157:43186 - - [19/Mar/2020 18:20:22] "HTTP/1.1 GET /jp" - 303 See Other
::ffff:192.168.5.157:43186 - - [19/Mar/2020 18:20:23] "HTTP/1.1 GET /login" - 200 OK

But get an unable to connect on the latest version of the app.

When I scan for a site from the app, it finds the right IP, but shows the firmware version of the site as 0.0.NaN

I am using version 4.0.23 of the SIP software from Git dated 2020-03-09 and the Feb 3, 2020 of the Android OpenSprinkler App.
