Can't connect to OPNsense's OpenVPN
Today I ran into a problem when connecting to an OpenVPN server running on an OPNsense firewall.
I received the following error message:
Decoding PKCS12 failed. Probably wrong password or unsupported/legacy encryption
I tried to reset the password, but that didn't have any effect.
After a short research, I found the following issue: OpenVPN-Gui 2.6 unable to decrypt .p12 file created in Client Export
So this seems to be a compatibility problem with the OpenSSL libraries of OpenVPN GUI 2.6 and OPNsense. After downgrading to OpenVPN GUI 2.5.7, the problem was gone for me. I hope they fix this soon.
