Error 500 on epg.xml - Plex cannot see any channels or tune in

[SgtBreadStick]

So i've spent quite a few hours figuring this all out and i'm still stuck with the same issues.
Below is a few snippets of errors that appear. I have tried with both digest authentication on and off

Not sure on what else I can do to solve the issue.

Here's the .env file contents if that helps

TVH_BINDADDR="0.0.0.0"
TVH_BINDPORT=5004
TVH_URL="http://localhost:9981"
TVH_PROXY_URL="http://localhost:5004"
TVH_TUNER_COUNT=1
TVH_WEIGHT=0
TVH_CHUNK_SIZE=1048576
TVH_PROFILE="pass"
TVH_USER="kieran"
TVH_PASSWORD="password"
TVH_PROXY_HOST="localhost"
TVH_PROXY_PORT="5004"

I tried using tvheadend with the --noacl argument and it seems to have temporarily solved the issue, however it's not that great of a solution.

Hey, how did you fix the first error ?

Using --noacl for tvheadend doesn't change anything for me unfortunately ?

EDIT: Nevermind, as you can see I added double quotes around the url (baisc docker-compose mistake)

For anyone in the future that finds this:
The easy way to fix this issue is to create 2 lines in your .env file

TVH_USER="username"
TVH_PASSWORD="password"
