Invalid URL? - Githubissues

When trying to load a valid URL (it works in firefox), the ics integration tells me that it is an invalid URL and no data was received. The Home Assistant logs contain the following. I have previously used this integration with the same calendar, so I know there's a way to get this working. Previously I was running Home Assistant OS on a Raspberry Pi, and am now running Home Assistant Container on an x86_64 architecture.
