After upgrading to 26.7 I lost an access to webgui (https) and pkg stopped working correctly. I think I've found reason for this issue but not a root cause. Anyway, as long as in System - Trust - Settings - MinProtocol (DTLS) is set to "DTLSv1.1" webgui and pkg doesn't work... After changing it (had to switch webgui to http) to None or DTLSv1 all works again!
