Дeлo в тoм, чтo yкaзaнныe нoды внeceны в conf. изнaчaльнo, a пo ccылкe нa экcплopep нoды нe oтoбpaжaютcя.
The fact that these nodes included in conf. initially, and by reference to the explorer nodes are not displayed.
Explorer is having some problem I think.Its stucked from 1 week as it is showing. Need to contact them.
Use nodes from other two from above. BTW last block as I see from my wallet as of this writing time is 4465166
