After months of everything working fine, I upgraded one of my nodes to 1.8.0 (via the plugin manager on FreeNAS).
The other side is a Mac, running 1.7.0.
Now I see this on the 1.8.0 side: " 2020-08-18 20:05:43: Bad certificate from atto at 172.16.0.2:38865-220.127.116.11:22067/relay-server/TLS1.3-TLS_AES_128_GCM_SHA256: x509: certificate relies on legacy Common Name field, use SANs or temporarily enable Common Name matching with GODEBUG=x509ignoreCN=0"
and it won’t sync. Any ideas?
