I have the same recorder (8Ch) her in our demo roundup.
I upgraded today from 3.210.0002.0 to 3.210.0003.0
I didn´t used push for the old firmware for months, but it had worked before. Now after upgrading I also can´t subscribe anymore. But only on this one. I will look later on at home on my other Android devices, if it´s possible.
You should better change the thread topic in something like "NVR 5xxx-4ks2 push subscription failing". Yours is too unspecific.
