Can somebody explain this error, please?
Error : Network Error - Network error downloading icon : getaddrinfo EAI_AGAIN api.cloudron.io
I have IPv6 configured on that box, so not sure where this error comes from suddenly.

I have disabled IPv6 in Cloudron for now and the error has gone.
So you had ipv6 properly working on the system itself, but Cloudron had some issue? Was this from a whole Cloudron restore, where maybe the network interface may have changed? Does it work after reenabling it?
You can try ping6 ipv6.api.cloudron.io and see if that works. Without it, IPv6 won't work.
