Hi SolarJeans ,
For 15.1.x OS version following ciphers will get impacted , see the last column for 256 or 384
when you will disable
disable-algorithms "." { "ECDSAP256SHA256"; "ECDSAP384SHA384"; };
If any of the keys using these CIPHERS will cause error till the key validation time not expired based on ttl.
