Unable to access HA Frontend in 0.78

I upgraded to 0.78 from 0.75, and when I try to load the front end, it says 404: Not Found

I checked the logs, it errors something saying “access_tokens”

Any help is much appreciated!

core-ssh:~# hassio ha info
“result”: “ok”,
“data”: {
“version”: “0.75.3”,
“last_version”: “0.78.3”,
“machine”: “raspberrypi3”,

“custom”: false,
“boot”: true,
“port”: 8123,
“ssl”: true,
“watchdog”: true,
“wait_boot”: 600

it says the version i 0.75.3, and last version is 0.78.3
