No Connection with 0-7-33

[ProfHaase]

Hi there,

Since the update to 0.7.3x I have the problem that I can no longer establish a connection. With version 0.7.29 it works without problems.
The log says the following:
2022-02-02 20:41:21 OpenSSL: error:0308010C:digital envelope routines::unsupported
2022-02-02 20:41:21 MGMT: Got unrecognized command>FATAL:Message hash algorithm 'RSA-SHA512' not found
2022-02-02 20:41:21 The encryption method of your private keys/pkcs12 might be outdated and you probably need to enable the OpenSSL legacy provider to be able to use this profile.
2022-02-02 20:41:21 MANAGEMENT: Client disconnected

2022-02-02 20:41:21 Process exited with exit value 1

I use openVPN 2.5.5 as server on a current OPNsense.

What is the difference in the versions that caused the error message or what can I/must I do?

Many Thanks

RSA-SHA512 should be just SHA512. OpenSSL 1.1 seems to have accepted this in the past but it is not really a hash algorithm and so OpenSSL 3.0.1 no longer recognises it as one.

Thank you, this helps me :-)
