Unifi Switch Unable to SSH to device

I had a really strange situation where i was unable to adopt a unifi switch that had been offline for some time. When i tried to SSH to the device,

I found that I had to use the following command to get into the device via SSH.
ssh [email protected] -o HostKeyAlgorithms=+ssh-rsa
Once i added the -o HostKeyAlgorithms i was able to use SSH like normal.

Then when I was attempting to find the firmware files on Ubiquiti’s site, i found that they have hidden the page. After a bit of searching on Reddit, i found the link. It’s here https://www.ui.com/download/releases/firmware

I proceeded to go through numerous updates from 4.0.66 to 4.3.22 to 5.43.23. Once i got there, i attempted to re-adopt the device, and bam, everything started working like normal!

HP MSA Management Unresponsive

I was having a problem with my HP MSA 1040 not responding to the management web page, so I found a tech article that said if you SSH into the system and run the following command, you can restart the management controller to get the page to come back up. It took about 2 minutes for the system to restart but eventually it came up
