I have > 30 Netgear M4100 and M4300 switches and some GS110TP in NMS300. Everything works fine (backups&management). I want to add some GS728TPv2 (set different credentials) and try to discover it with new credentials and I have Credentials failure. I tried SSH, HTTP, HTTPS. Only SNMPv1/2 works fine, but I can't make backups with SNMP only.
NMS300 version 1.7.0.12
Model: GS728TPv2|24-Port Gigabit Ethernet PoE+ Smart Managed Pro Switch with 4 SFP Ports (190W)
It seems that you are having issues with your NMS300. May I know if all the backups are not working in any other protocol except for SNMP? Is it not working on all devices or there are specific backups that are not working? May you be able to provide some screenshots?
Only GS728TPv2 doesn't work. I can only discover it over SNMP. All others switches comunicate with credentials set at Default credentilas. GS728TPv2 has different web/cli password so I've added new credentilas and perform Quick Discovery and had Failure credentilas.
Some screenshot below.

Please do upgrade the firmware of the GS728TPv2 or re-flash the firmware if it is already running on the latest version then reset it to factory default then re-add it to your NMS300.
Our L3 engineers suggested having a packet capture when you try to do a backup job with the GS728TPv2 so that we can check what is happening and have it escalated.
