I have a Raspberry PI 5, running NodeRed on stock raspberry PI OS, deployed on a site.
The site, and my home for that matter, are both on 4G internet connections (UK).
The RPI, my lappy and a tablet have all been using a Zerotier network for weeks and preforming very well when viewing the NodeRed dashboard or the PI Desktop, from either machine. In addition there are another couple of devices, different people, occasionally looking at this same site.
2 days ago there was a prolonged power cut and since then the connection has been so slow as to be all but unusable. I did manage to get VNC to load and ran an internet speed test from the PI, eventuallyā¦ It reported well over 20mbps and the occupier of the site said his internet was fine, subjectively, HD videos were working and web pages loaded quickly.
I have since been to the site and the PI is fine, as is the internet connection. I added āRaspberry connectā so I have another way to access it, avoiding the CGNAT issue and that seems fine too.
However, if I try to view NodeRed in a browser from anywhere outside the sites LAN, using the Zerotier network, it is still crazy slow!
Is there anywhere I can look at logs/errors? What could be causing this? As far as I am aware its a basic stock setup with all authorised devices manually assigned different IPās and no routing enabled! Moreover its been great for weeks and other than a power outage for about 12 Hrs, nothing has changed.
If I am on the site, plugged into the LAN, a direct connection is fine and so is the Zerotier network connection but I am assuming that is because the two devices are instructed to directly communicate by the Zerotier connectors.
I have a basic working knowledge of networking but nowhere near the knowledge/skill necessary to even understand how Zerotier is working when it works, let alone to try and find out why it isnāt working.
Please help if you can, I had just about decided to move all my sites to a paid for Zerotier network/s, because testing has been so solid, but this has caused me significant issues.
The chat bot tells me I will need a commercial account before there is any support, that makes evaluating support somewhat hard to do!
This is the first issue I have had, but its a game changer without an explanation!
I have literally just asked a UK company to look at designing an ARM based board to run Linux / docker with, amongst other things, a Zerotier appā¦ The goal is remote site monitoring and control that will work anywhere with an internet connection and require no local network configuration.
I realise giving direct support to everyone with a free account isnāt realistic but I am hoping that something this odd, and fundamental, can be addressed, if only to give me confidence to move froward with a commercial rollout, all be it a modest one!
