Is the Hadith describing lunar and solar eclipses as signs of Mahdi's arrival authentic?

I recently read the following hadith regarding the arrival of the Mahdi. >اِنَّ لِمَهْدِيَّنَا آيَتَيْنِ لَمْ تَكُوْنَا مُنْذُ خَلْقِ السَّمَاوَاتِ وَالأَرْضِ، تَنْكَسِفُ الْقَمَرُ لأَوَّلِ لَيْلَةٍ مِنْ رَمَضَانَ، وَ تَنْكَسِفُ الشَّمْسُ فِي النِّصْفِ مِنْهُ، وَلَمْ تَكُوْنَا مُنْذُ خَلَقَ اللّٰهُ السَّمَاوَاتِ وَ الأَرْضَ > > “For our Mahdi [Spiritual Reformer] there are two signs which have never appeared before since the creation of the Heavens and the Earth, namely the Moon will be eclipsed on the first night in Ramadan [i.e. on the first of the nights on which a lunar eclipse can occur] and the Sun will be eclipsed on the middle day [i.e. on the middle one of the days on which a solar eclipse can occur]. And these signs have not appeared since God created the Heavens and the Earth.” (Sunan al-Daraqutni, Kitab al-Eidain) According to Islamqa, the hadith is fabricated but i cannot find any other source claiming this. Is this hadith authentic at all?
