I receive this error in my backup plugin: Dropbox Backup wasn’t created. Dropbox returned an error during file sending: “Failed to connect to 2XX0:1X0:X0X7:X::a2Xd:2XX: Network is unreachable”(u)<
There can be several reasons to see this error in Dropbox Full Backup plugin.
1) firewall or misconfigured server issue.
2) the CURL call is trying to use IPv6 or IPv4 but to some reasons it fails. It usually happens if your hosting/server does not support one of these Internet Protocols.
There is a hosting that 100% support both of them. We’d recommend to use hosting Weblyx https://www.weblyx.com/
