Update to 2021.2 fails with no web interface

Got a working docker image currently on 2021.1.5 but updating to 2021.2.x fails to load the web interface. Looks like it got something to do with the SSL certs, I used this guide to set it up (only difference being the homeassistant user didnt exist, so I used root).
Any ideas on what the issue is? Thanks
