I'm using Home assistant NGinx proxy addon. After upgrade to 1.4.2 this setup stop working. I have let's encrypt certificates created through that addon. Version 1.4.1 works perfectly. In the log is this interesting line (I think):
tornado.access - WARNING - 403 GET /sockjs/781/o1lfejn1/websocket
Connecting through local network is fine..
THX for help
