Hi, after having solved this problem some time ago, i have a similar problem, not every 12 hours but after some days my new server from IONOS with ubuntu 22.04. is completly away, no ssh access not plesk. Only solution is to reboot via ionos cloud panel. it is a dedicated server. problem is i allready tryed 3 servers of this kind Ryzen 9 Pro 3900, 128 GB Ram, NVME and Ubunut 22.04 with plesk. Alle had the same problem.... works like 7-10 Days then even when there is no load at all, putty closes (lost connection) and like disconnected from ethernet... after one reboot everything works again for some days .... i cant find anything in the logs. Anyone else maybe with a similar problem?
