Hi guys. I found an issue where it seems that the LDS cannot handle certificates with >2048-bit RSA keys.
Beforehand, I only tested this with 2048-bit and 4096-bit RSA keys, none other. I used LDS standard configuration.
It seems that the RegisterServer2 request is not sent when the server, which wants to register, uses a certificate with an RSA key of 4096-bit. So I compared the configuration with an OPC UA sample server and found out that the problem was the key length. I tried this again with a certificate that contains a 2048-bit RSA key and this worked just fine.
I haven't looked into this deeper, so I can't say if the issue relates only to the key size or other things as well.
Attached is the wireshark trace.
