Where can I get Open VPN connect version 3.4.2 ? It seems to be the only version, that we can use to connect to our VPN on macOS Ventura 13.6.3 and the latest version of macOS Sonoma.

With OpenVPN Connect 3.4.3.475 we get the following error:

Code: Select all

With OpenVPN connect 3.4.2 I get the following warning, although the connection is working.

"WARN TLS: received certificate signed with SHA1. Please inform your admin to upgrade to a stronger algorithm. Support for SHA1 signatures will be dropped in the future"

We also tried OpenVPN Connect v2.7.1, this version also failed to connect.

Has OpenVPN Connect >= 3.4.3 removed the support for SHA1 signatures? I can not see anything mentioned in the below changelog.

I must admit, I do not want to change anything regarding the server certificate, if I do not need to. At this time only one user can not use the VPN. It would be a catastrophe, if no user could use the VPN....
