Oxley Solar Data upload

Hello, i have 2 identical solar systems on one roof. Both with one inverter SMA 5000. Data ist transfered each 5 min by Oxley solar pro to pvoutput.org system names Wiesenhalde6 links und rechts. The Android cell Phone is placed in the near of the Inverter and does nothing else. Worked fine for years but since 2 months one system (links) is not updated each 5 min. If i use Stack Upload it works fine. In the night data is transfered and in the next morning Data of the former day is available. Does anybody have an idea?

I’m thinking of 2 things to check out, is the date on both inverters set correctly? Also how about power cycle both inverters as I found that fixed an issue with my SMA once.
