Managesieve Plugin appears to be broken after 1.6.0-rc upgrade

After upgrading to 1.6.0-rc I can't use the managesieve plugin.

[27-Jun-2022 10:08:56 -0500]: <48af0189> PHP Error: This server doesn't support any authentication methods. (GET /webmail/?_task=settings&_action=plugin.managesieve)

If I revert back to 1.5.3 it works fine, confirmed all settings, and tried playing around with different options but nothing appears to have any impact.

$config['managesieve_host'] = 'tls://localhost:4190&#39;;

Thanks, that fixed it, this was set lower in the configuration file:

$config['managesieve_usetls'] = true;

I guess either that is no longer applying or the fall back port of 4190, is not working anymore.
