v2 is a Duplicati naming invention to distinguish the Microsoft Graph version from original which is gone. OneDrive failing : “The remote server returned an error: (410) Gone.”
That’s an example of the brand continuing but its underlying technology changing. We’re in a tech issue.
There are other tests and answers that I’m more interested in though, so it’s fine to defer this, if needed.
Compare OneDrive cloud storage pricing and plans shows at least a marketing split between consumer products and business products, then the link for Enterprise shows some other options. I think business product line uses Sharepoint technology underneath to give it a different feature set, and this may matter.
The LiveConnect API this backend is based on is deprecated and will be disabled on November 1st, 2018. New backups to OneDrive should be created using the OneDrive v2 backend based on the Microsoft Graph API, and existing backups should be migrated.
not free, this is a business account with a onedrive plan 2 license so seeing as it cannot now upload anything using duplicati i think its a server, network issue, i have a NAS onsite and install Duplicati to that and that can back no issues at all.
tried to implement a few different PCI configurations in the event it was a cypher issue but nothing helped there.
tried to run Duplicati as a admin user instead of service no difference
removed anti-virus - no difference
i am at a complete loss, i have around 30 servers all running Duplicati and this is the only one causing such headaches.
at this point I’d say that the best way is to compare with the other working Duplicati servers to see what is common or not: OS, .Net version, Duplicati version, network (Cloud backend, internet provider, router and firewall, network stack on the OS)
so i have check against another server and cannot see anything different in terms of hardware or windows configuration, that includes Cipher suites, .net version etc, BUT this server that is failing does have different software running on it.
so i have done a wireshark capture of the backend test, i can see an initial connection all ok, then from Microsoft end RST, ACK, so the connection is being reset. i have the wireshark log saved but have no idea really how to read these
OK, a little reading is dangerous.! so RST, ACK is basically saying that the port is closed. IF that is the case it would suggest that Duplicati is making an outbound connection from port 443 to MS on a port 16470
but MS tries to talk back to the server on the same 16470 port but cant. kind of suggesting the established port is being closed
A first check might be see if it got at least to where its setup is complete and application data is flowing.
Unfortunately for debug (but good for security), encryption prevents you from seeing Duplicati’s actions.
In theory you could post the Wireshark capture and reveal not a whole lot (mostly some IPs and MACs).
