After updating hummingbird I'm getting this error:

Is this a known bug or an expected breaking change? Do I need to revert to a previous version of hummingbird? I have updated all the system packages with

Quote

sudo apt-get update && sudo apt-get upgrade

but the problem persists.

Hello!

AES-CBC is no more supported, please switch to AES-GCM or CHACHA20-POLY1305. You can edit the ovpn file with any text editor or you can generate new configuration files. If you do so, make sure you select "OpenVPN >= 2.5" in the proper combo box of the Configuration Generator page: the CG will generate files including no references to AES-CBC.

Kind regards
