So it seems that it's the orangepi itself which is taking down the network, as soon as I turned it off everything else started to work.
Unsure what is happening here but it's not great - next step will be to boot it up, back it up and then reinstall Linux.
Solarcene will be offline for a little while longer, sorry
I've started work on getting the system back online, currently I've got the orangepi offline and am exploring whether my #pinephone could be used to host some of the services. I used jump drive to install the latest stable #postmarketos to the eMMC, enabled ssh, installed a number of dependencies and currently am slowly installing ruby to see if mastodon might actually work (it should fit within the specs, just)
Actually quite fun
Update:
I've moved gitea off the orangepi5 and have it now working well on my #pinephone which is connected via usb ethernet to the network, it's running #postmarketos and seems to be handling it well https://git.solarcene.community
The mastodon instance is still on the orangepi and while it does keep resetting it seems to be reasonably stable, it's all backed up, I'm still planning what to do next, I might build a second server and then move everything across. Still not sure what's made the #orangepi5 unstable after over a year of running
@EarthOrgUK it uses a SD card to boot but then runs off a nvme drive so should be okay, it could be a power supply issue though.
I think my plan to build a replacement server and then once solarcene.community is stable again I can then investigate what's gone wrong with the original
